DESCRIPTION
Wrong connection between the pump
and the controller (P31).
The interlock signal of P1 connector is
activated by an interruption of the link
between pin 3 and 8 of J1 connector, or
because the external interlock signal is
open.

speed of 5500 KRPM 12 minutes after
startup with SOFT START deselected.

the following threshold values:
- 65 °C for the bearings
- 90 °C for motor.
- 60 °C for the water.
The controller transformer temperature
exceeds 90 °C or the temperature on the
outgoing

radiator
60 °C.
In normal operation (after the starting
phase) the current drawn by the pump is
higher than programmed (25 A)
After the starting phase the output
connection is shorted (output current
higher than 60 A).
The pump is stopped by an emergency
stop signal provided via a remote
contact.
