Listed below are a series of questions and answers related to using the Cellular Machines Temperature Monitoring System. If you have a question about the system, using it, or are having an issue that cannot be solved through the information below or the information provided in the Installation and Operation User’s Manual, please contact us.

Updates made to the control station’s firmware are done remotely via an over-the-air (OTA) update, up to firmware version V5.12f. While the control station’s firmware is being updated, it cannot be used until the update is complete. Additionally, the system may need to be reconfigured afterwards, including re-syncing wireless pods, entering sensor information, or performing a factory reset. Whenever firmware is updated, a notification email will be sent to the Temperature Monitoring System owner’s email address informing them of the update and the changes that have been made.

NOTE: In the event of a power outage during an OTA update, the control station’s internal backup batteries will power the device. If the batteries are out of power, or if the control station becomes disconnected from the power supply, the update will fail and the current firmware will remain active.

No components of the Temperature Monitoring System should be installed outdoors. The components are designed to be installed in controlled environments only. Installing any components outdoors or in areas that may expose them to hazardous materials may subject them to damage or failure. However, system components that require an outdoor installation can be outfitted for such conditions. To explore customization options and component outfitting, contact us.

Only the temperature sensor can be safely located in conditions of high or low temperatures. Neither the control station nor the wireless pod should be installed in such conditions. Environments with extreme temperatures may affect these components’ ability to function, and can damage or corrupt the hardware inside them.

Only the temperature sensor can be safely located in conditions of high humidity. Neither the control station nor the wireless pod should be installed in such conditions. Environments with high humidity may affect these components due to moisture build up inside them. If this occurs, it may risk damaging or corrupting the hardware inside these components.

The only means to completely remove power to the control station is by disconnecting it from the power supply. This will shut down the control station completely and prevent it from reverting to using its internal backup batteries to maintain power. If the control station is off, connecting it to the power supply will turn it on again.

The control station’s internal backup batteries have a lifespan of approximately 15-20 hours, and are not rechargeable. If the batteries runs out of power, or if the control station’s Low Batt LED is on and an alarm is received indicating low battery power, contact Anaren Customer Support to arrange to have them replaced. If the control station has been operating on its internal backup batteries for an extended period of time and you wish to preserve its battery power, disconnect the control station from the power supply to shut off the control station.

NOTE: Shutting off the control station will shut down the rest of the system and its alarming functions. Do so at your own risk. If the control station is off, a note that it is off the air will be indicated on the cloud server, and an email notifying the system owner that the control station is off the air will be sent.

Replacement batteries will need to be ordered for the control station. Contact Anaren Customer Support to purchase and arrange to have the control station equipped with new internal backup batteries. In general, in the event a power failure occurs and it is unlikely to return within a reasonable period of time, disconnect the control station from the power supply to shut off the device. This will stop the system from monitoring the equipment, but will preserve its internal backup battery power.

The wireless pod comes with four AAA 1.5V alkaline batteries, which have a battery life of approximately five years. To replace these batteries, unscrew the pod’s enclosure to open it, then replace the batteries with four new AAA alkaline batteries. For pods that operate in cold environments, it is recommended to use lithium batteries instead.

Yes, rechargeable AAA 1.2V batteries can be used in the wireless pod. There will be little or no noticeable difference if rechargeable 1.2V batteries are used instead of 1.5V alkaline batteries. However, rechargeable 1.2V batteries may experience a steep decline in power once they near the end of their charge, and the lifespan may be shorter than that of an alkaline battery. If using rechargeable 1.2V batteries, it is recommended to change them immediately if a “battery low” alarm is detected to prevent the pod from losing power.

Up to 16 wireless pods and/or temperature sensors may be connected to the control station, with a maximum of four sensors per pod. Additional pods can be added, or sensors can be added to existing pods by using a combiner.

If a wireless pod is being synced to the control station, all pods connected to the system (not just the new pod) must be re-synced. A pod that is not re-synced will not be recognized by the control station. Otherwise, the pod may be too close to the control station and cannot properly connect; a distance of at least six feet must be between the pod and the control station. Additionally, the maximum number of pods that can be synced to one control station is 16. Any number beyond that will fail to sync to the control station.

In order for a control station to recognize an additional (not to be confused with replaced) temperature sensor connected through a combiner, the wireless pod must be re-synced to the control station. Otherwise, the new sensor will not be displayed on either the control station or the online user dashboard. Note that if this is done, all pods connected to the control station must be re-synced.

A temperature sensor is assigned a default number based on the number of its associated wireless pod and the number of sensors connected to it. In 16-sensor maximum systems each pod is allocated specific numbers for their sensors, and the assigned number of the sensor does not necessarily appear in numerical order. Sensor names may be changed, so this impacts the default numbers given to new sensors only. However, these default numbers are always displayed on the Cellular Machines online user dashboard next to the sensor name field, regardless if the sensor’s name has been changed.

A temperature sensor’s probe collecting moisture during a defrost cycle will not have any detrimental impact on it. The temperature probe is protected and designed to endure these types of conditions. However, if moisture collects and permanently freezes on the temperature probe, or the temperature probe is in standing water, that can affect its ability to accurately measure temperature. Temperature sensors should be checked regularly to ensure they are in proper working condition.

The signal reception of the control station may be poor. Check the cell signal of the control station on its scrolling status menu and verify it is in an acceptable range of two or three bars. One or no bars will result in little or no connection, and the control station may have to be moved to another location to improve its signal reception. Likewise, if a wireless pod is displaying too low of an RSSI, it may have to be relocated as well.

Check the equipment manufacturer’s website or user manual for information on recommended temperature limits and proper use of their equipment. For state and federal requirements on regulated temperatures for certain products and inventory, visit the Food and Drug Administration website at www.fda.gov, or the website for the regulating agency of that particular industry.

When updating parameters through the online user dashboard, the control station will update during its next scheduled logging interval. Check the frequency of the logging interval to determine when the parameters will be updated on the control station. The control station can immediately update parameters by forcing it to log a message to the cloud server. Steps to force a cloud server log are outlined in the Installation and Operation User’s Manual.

It is unlikely that the temperature sensor itself is defective. Instead, a setting for the equipment in question may need adjustment, or the location of the sensor itself within the equipment. Logon to the online user dashboard, and view the data report of the equipment responsible for the alarm during the length of time this has occurred. Analyze the data for any patterns or consistencies that may help determine the exact cause for the alarm. Common instances of these patterns include certain days of the week, time of day, and frequency of equipment use. Daily defrost cycles or refrigerator temperatures settling overnight or during long periods without use are two such examples. These instances may provide insight into adjusting the settings of the system to reflect the conditions of the equipment during these times. Alternatively, if the sensor is located in an area prone to fluctuating temperatures (such as near a compressor or very close to a door), it may inaccurately measure the equipment’s temperature and should be relocated to a more centralized area. If the alarm issues are not the result from a system setting or location of the sensor, there may be a potential issue with the equipment itself.

Temperature sensors can sometimes react quickly to events (such as a door opening), resulting in unwanted alarms. This can be avoided by either adjusting the alarm delay time for the sensor that is detecting the temperature change, or by installing a dampener to the sensor. The sensor dampener provides a thermal buffer for the sensor, and “slows”the sensor’s response time to such temperature shifts.

The communication between the wireless pod and the control station may take up to two minutes to be established based on their signal reception. If more than two minutes pass and the error status remains unchanged, check the original source of the issue to verify it has been corrected.

The Temperature Monitoring System includes an alarming hysteresis in order to mitigate continuous setting and clearing of incidental alarms when temperatures hover near a threshold. This hysteresis is set to 2° Fahrenheit or 1°Celsius. Whenever a temperature alarm is triggered, it will not be cleared until it is beyond the hysteresis of the temperature scale used. In this example, the temperature must drop to 43° Fahrenheit in order for the alarm to be cleared.

When any monitored equipment is subject to an environmental change, either from service, maintenance, or any other means, the settings for that equipment should also be modified to reflect those changes. This will prevent unnecessarily alarms from being triggered and receiving false alerts. Likewise, after any monitored equipment undergoes a period of change, it is important to return its system settings to what they previously were afterwards, or adapt them to any updates the equipment has gone through. Not doing so may result in inaccurate temperature readings or alarms, or failure to detect a harmful condition.

The mobile phone number may have been entered incorrectly, or the settings for either receiving text message alarms or that particular alert type might not be enabled on the control station. Ensure all mobile phone numbers are properly entered on the control station, and verify the text message alert settings are configured to your liking through using the control station’s menu options.

Verify the control station’s alarm buzzer is enabled through the main menu. Likewise, check if the control station is in silent mode. If the control station is in silent mode, it will override the alarm buzzer if it is enabled, and no sound will be made if an alarm is triggered.

No. System parameters will need to be manually configured again. However, the online user dashboard stores wireless pod settings, so when pods are re-synced to the control station they will be reconfigured automatically after the first logging interval.

NOTE: The online user dashboard will populate pod settings based on the order the pods are listed. It is recommended to re-sync pods in the same order as they originally were in so the pod settings will be applied to the same pod.

Yes. The online user dashboard can be accessed from any browser and from a personal computer, tablet, or mobile phone.

When a new Temperature Monitoring System is installed and activated, it may take up to one hour for the cloud server to receive temperature readings and status for the first time (reporting via graphs may take slightly longer). After this initial instance, the cloud server will update during every logging interval, any time an alarm is triggered, and whenever a text message alert is sent. Otherwise, verify the control station has the UDP logging function enabled. If this function is disabled, no information will be sent to the cloud server and it cannot be viewed through the online user dashboard.

Refer to the Installation and Operation User’s Manual for installation guidance to help maximize cellular reception capabilities. If cellular reception is poor and cannot be helped through installation or device location, contact us to seek an alternative solution.

No. The Anaren monthly data plan is a flat rate for all packages and contains a sufficient amount of data and text message allowance to cover system operation. The differences in data plans are within the length of the plan’s contract. Data plans do not include any data or service capabilities for personal mobile phones. In the event a control station alarms at an unusually high rate, contact Anaren Customer Support to bring the system’s performance in-line. In extreme cases, Anaren reserves the right to modify the system’s settings to comply with reasonable data and text message usage policies. If Anaren’s solutions for modifying system settings due to extreme data and text message usage are ignored or bypassed, Anaren reserves the right to apply additional charges for text message and data overages.
