Fig. 23: Temperature sensor - TS2
Cooling units with Multi-Controllers (MC) are equipped with an energy-saving module.
The Multi-Controller (MC) therefore has a connection for a second TS2 temperature sensor (1).
The TS2 temperature sensor (1) is installed externally on the cooling unit and monitors the switch cabinet interior temperature.
4.6.6.1 Connecting the external temperature sensor TS2
Prerequisites
DANGER – Danger to life due to electric shock. Make sure that the unit is voltage-free.
Procedure
1. Plug the connecting plug (2) into the mating plug (3) on the cooling unit. The mating plug (3) is labeled with X51 in the
electrical circuit diagram, see "Electrical circuit diagram – Multi-Controller (MC)", Page 42.
2. Position the TS2 temperature sensor (1) in the switch cabinet and fix with a cable tie.
• It is recommended to position the TS2 temperature sensor in an area in which the greatest heat development
takes place.
The external temperature sensor TS2 is connected.
