5.1 remote start/stop control - premium controller
To gain access to the remote start/stop feature:
• Open the enclosure door, this will then expose the controller
• Remove the insulation from the ying lead
• There are six wires; 1. Red Wire - 24V Output (24V+)
2. Blue Wire - 4-20 mA Output (420-)
3. Black Wire - Remote Start/Stop (RMS)
4. Yellow Wire - 4-20 mA Output (420+)
5. Green Wire - Alarm Output (ALM)
6. White Wire - Emergency Stop (EMS)
• To set up the Remote Start/Stop control, remove/break the connection between the Red & Black wires and connect
externally to a remote switch or relay.
• A 24V DC Output must be connected to the Black wire to enable the dryer to operate, if the connection is broken or if there is
no voltage the dryer will switch off and revert to standby mode, displaying “REMOTE STOP ACTIVE” on the controller display.
Under no circumstances should an external voltage or current be applied to any of these wires, as damage to the
control system will occur, negating the warranty.
