If a fault/ alarm occurs, the Acknowledge button (on the Main Screen) and the
temperature zone will be highlighted in red. The controller will turn off the internal power
to the heaters and an appropriate alarm indication will appear in the status line of the
controller’s display.
The operator must either turn Off the indicated temperature zone(s) or troubleshoot to
correct the problem. Then press the Acknowledge button in order to turn on the main
contactor and reset the error. If more than one alarm condition occurs simultaneously, the
alarms will be displayed sequentially and each alarm must be acknowledged.
When an alarm occurs, the current display will be interrupted only if a sensor (or a motor
drive) failure has occurred. When the actual temperature exceeds the setpoint limitation
(plus a tolerance) the over-temperature alarm is displayed and main power is switched
Off.
Sequential Heating
The heating sequence allows the slower-heating platen to reach operating temperature
without unnecessary use of electricity for faster-heating hoses and applicators.
Sequential heating is the time period during which the hoses and applicators remain OFF
while the platen heats up. Hoses and applicators may be independently programmed. If
platen temperature is above ready temperature when the ASU is turned ON, the hose
and applicator sequence is bypassed and they will be turned ON. Sequential heating is
restored after Standby is turned from ON to OFF. Sequential heating is not needed for
most applications and can delay total system warm-up time.
