Digital input connection (DIG IN)
Terminals 3 and 4 are intended for an external closing contact. The input is galvanically
isolated.
Terminal 4 is the common signal ground for terminal 3 and terminal 5.
The functions for the digital input that can be selected in window 53 are:
1. High level switch (to enable immediate start of the pump)
2. External Reset
3. External Auto-set
Terminal 5 connection (e.g. temperature supervision)
Terminals 4 and 5 can be used for temperature supervision: a thermal contact or a PTC
thermistor. As an alternative the terminals can be used with any device using a voltage-free
opening contact such as a motor protection unit.
Terminal 4 is the common signal ground for terminal 5 and terminal 3.
