Function
S3 (13-5)
Stand-by
1)
Contact closed: Stand-by speed is selected.
Contact open: pump rotation speed is the nominal speed.
S4 (14-5)
Start/Stop pump
1)
Contact closed: the pump starts.
Contact open: the pump stops.
1) This function runs when the control mode is set to ‘Remote hard’ via the RS-232/RS-485 serial link
(see chapter “List of commands”) or via HHR (see chapter “SETUP menu”).

Relay At Speed Contact closed: OK for Process (at speed)
●
M version
: speed ≥ nominal speed (set by ‘Relay At Speed’ pa-
rameter) (see chapter “SETUP menu”) or (see chapter “List of
commands”).
●
MT version
: speed ≥ nominal speed (set by ‘Relay At Speed’
parameter, (see chapter “SETUP menu”) or (see chapter “List of
commands”), and if the temperature is ≥ the setpoint temperature
- 3 °C.

Rotation
Rotating mode OPT33 = 0
● The contact closes when the speed > 120 min
-1
.
● The contact opens when the speed < 100 min
-1
.
Accelerating mode OPT33 = 1
● The contact closes when the motor is in acceleration phase. It re-
mains closed until the nominal speed has been reached.
● The contact opens when a STOP or INHIBIT command is taken
into account or if the nominal speed has been reached.
To avoid misinterpreting the status of the contacts, we recommend a one-second filter on the reading
of At Speed, Rotation, Fault and Stand-by contacts.
