Watlow EZ-Zone PM Express Temperature Controller
The
Watlow EZ-Zone PM Express Temperature Controllers
are used to monitor and maintain a
target temperature range for the sealing shoes of the heat sealer. The heat sealer is equipped
with two controllers, which control the two sealer shoes (inside and outside) independently.
The temperature controllers are programmed at V-TEK prior to shipment. They use a PID tuning
loop to ensure proper temperature stabilization. If the temperature goes outside the pre-set value
by +/- 10 degrees or more, the controller will flash an alarm display.
• If the display reads
AL.hl
, the temperature is too high.
• If the display reads
AL.Li
the temperature is too low.
The TM-500 cannot operate when a temperature alarm is triggered. If the TM-500’s
Start
button
is pressed when the temperature controllers are registering a Temperature Fail alarm, a
“Temp
Fail Alarm has been raised.”
message will appear on the TM-500 HMI display.
