In low voltage applications of CALEC
installation, the adapter "insulated supply 24V-24V» (Art. no. 80828) must be positioned
upstream.
Examples for grounding:
• Grounded pulse input (e.g. pulser AMFLO
• Grounded sensor supply 3.6V and / or 24V
• Grounded pole of the low voltage supply
Procedure:
1. Disconnect CALEC ST II from power supply
®
2. Set switch S4 from left to right
3. Connect adapter:
108+ from adapter to clamp 108 on CALEC
109- from adapter to clamp 109 on CALEC
IN+ and IN- from adapter to the external measuring point supply
Additionally the low voltage and sensor supply is possible with the adapter "insulated supply
24V-24V». Therefore the sensor shall be connected with OUT2+ and OUT2- (max. 150 mA).
If the switch is not correctly set, the device is later may not working properly or getting
destroyed.
The function low voltage supply shall only be used with the switch S4 in the position "right"!
