6.1.4 Operation relay connection (PUMP & C)
Terminals 7 and 8 are the operating relay connections that control the start and
stop equipment for the pump motor.
Terminal 8 (PUMP) is an operating relay output. Terminal 7 (C) is the
common input for the operating relay, see Fig. 13, page 25.
When powered off, the operating relay is NO . When powered on, NC or NO
can be selected, see Table 8, page 53 and window 52.
6.1.5 Digital input connection (DIG & SGND)
Terminals 3 (DIG) and 4 (SGND) are connections for a closing contact
between DIG and SGND.
The three functions that can be initiated by the digital input are:
1. High-level switch (to enable immediate start of the pump).
2. External reset.
3. External Auto set.
See Fig. 13, Table 8, page 53 and window 53.
6.1.6 Temperature-measuring input connection
(TEMP & SGND)
Terminals 4 and 5 are the temperature-measuring input and/or motor
protection contact connections. The motor protection relay can be connected in
series with the temperature sensor. Terminal 5 (TEMP) is for a PTC-type
thermistor or thermo contact. Terminal 4 (SGND) is the signal ground for the
temperature-measuring input. See Fig. 13, Table 8 and windows 31 and 32.
