Mechanical Temp Alerts, MTA-1, TA-1, TA-2HL
Q: Can these units be set normally closed?
A: No, They are all normally open devices.
Q: Can I use these units in freezers or coolers?
A: No, frost or moisture can cause malfunction.
WaterBug - WB200
Q: What is the cause if the unit keeps going into false alarm?
A: If the sensor is placed on a concrete floor this can cause false alarms. Also power loss will cause a false alarm.
Q: How much water does it take to trip the sensor?
A: You need enough water to bridge across two of the metal contacts on the sensor.
Q: How far can the sensor be from the module?
A: 100 feet per sensor, up to six sensors.
EnviroAlert - EA200-12, EA400-12
Q: Can the old TempAlert probes be used with the EnviroAlert?
A: Yes they can be, but you must use connector blocks to attach the probe wires to the EnviroAlert unit. (They must be purchased separate from the EnviroAlert unit. They come in a package with three connectors. Winland P/N E-003-0010)
Q: Does the Blue Low Temp Sensor have a blue tip?
A: No, it has a cylindrical stainless steel tip with a blue band at the base. We do offer a sensor with a blue tip (Winland P/N 1107). This sensor was used with our old Temp Alert models and it will work with the EnviroAlert but must be wired polarity specific, must use connector blocks for attachement (see previous question), and must be set up in the EnviroAlert programming as °C or °F (do not setup as °C Blue or °F Blue, probe will not function properly)
Q: Can you connect multiple temperature probes per zone?
A: No, you can only connect one temperature probe per zone. The same is true with humidity sensors, only one per zone. But you can connect up to six water sensors per zone.
Q: I ordered a Blue Low Temp. probe and received a Red High Temp probe instead. Why?
A: There was a misprint in our owner’s manual where the numbers for the Blue and Red probes were transposed. That error has since been corrected. The updated owner’s manual can be downloaded at www.winland.com. For clarification. the Red High Temp probe is Winland P/N M-001-0081 and the Blue Low Temp probe is Winland P/N M-001-0082.
Q: Are the time delay settings in minutes or seconds, and what is the purpose of programming a time delay?
A: First, the settings are in one minute increments up to 120 minutes. Second, in certain applications a time delay is an important feature to have to avoid false alarms. For example, freezers will go into a defrost mode where temperatures will rise above the low temperature setting. This in turn, would set the unit into alarm mode. But the defrost situation is expected and is not considered a problem, therefore there is no need to be notified of the alarm. If a time delay is programmed into the system and a freezer goes into defrost mode there will be no alarm until the maximum delay setting has been exceeded.
Q: Where should I mount the sensors for proper operation?
A: It depends upon what you are monitoring. If you are monitoring the ambient temperature of an enclosed area, find a point that best represents the ideal environment and is not affected by external influences (i.e. a draft from an open door). If you are monitoring a physical mass, make sure that the tip of the probe contacts the mass to be measured. Again, find a point that best represents the ideal environment and is not affected by external influences (i.e. direct sunlight). Most importantly, while routing the wire and probe avoid placing either near high voltage electrical lines or noisy electrical devices like electrical motors. Interference could occur and affect the functionality of the unit.
Q: I receive false alarms at midnight every night, but when I check the unit there is no alarm. Why?
A: This issue involved a glitch in the unit’s software. It only happened if you were using the zone in an energized state. This issue has since been fixed. To determine if you have the latest software, power down the unit, then power it back up. The screen will show the unit model number and the software revision. This revision should be at b1 or higher.
Q: Where should I mount the EnviroAlert unit for proper operation?
A: You can mount the unit to a two-gang electrical enclosure or flat wall surface. Please do not mount the unit near high voltage electrical lines or noisy electrical devices like electrical motors. Interference could occur and affect the functionality of the unit.
Q: Could you please explain how the high & low temperature settings work?
A: You must look at the ideal temperature range of the area your monitoring. Then set the high limit for a temperature above the high end of that ideal range. Then set the low limit for a temperature below the low end of that ideal range. If the measured temperature falls above the high and below the low settings the unit will go into alarm. Remember there is no alarm condition when the temperature sensed by the unit is between the high and low set points. An alarm condition only exists when the temperature sensed by the unit is above the high set point and below the low set point.
