3.3 Alarms

If an alarm is activated, the unit goes into Off mode until the problem is corrected.
If an alarm message is displayed in the PLC display, the light in the Standby/Running button flashes one second

on, one second off. This 1/1 on/off sequence continues until the problem is corrected and the alarm reset. The

backlight colour in the display changes to red while there is an active alarm.

3.3.1 External Fire Alarm Explosion Detected

An external fire alarm is activated or a Relief Panel Sensor (RPS) is connected and has detected an explosion.

Press the green OK button to reset the alarm.

3.3.2 Frequency Conv Alarm

The frequency converter has detected a problem and that the PTC sensors in the motor have reached the max-

imum temperature for the unit (140°C) so the unit has been put into Off mode.
The following list shows the most common problems:
• Connection problem to the main power supply.
• Motor cable problem.
• Power supply fault.
• There is a problem with the frequency converter.
• PTC temp monitor detects an overheated motor.

3.3.3 Emergency Stop Activated

If this message appears in the display, one or more emergency stops have been activated and the machine has

been switched off. External systems can be connected to the FlexPAK E-stop circuit, eg On the FlexPAK DX unit.

RPS panel sensor is connected.
Find out why the emergency stop has been activated and correct the problem. When all hazards have been elim-

inated that activated the emergency stop, the emergency stop can be reset. Reset the Emergency Stop Button

by turning it and then pulling it outward.
When all emergency stops have been reset, the security circuit can be reset by pressing the green OK button in

the display.
If the Green OK button can not be reset even though all emergency stops are reset, it may be due to a short cir-

cuit to ground in the emergency stop circuit or pilot signal circuit.
