PUMP WAITING
INTERLOCK
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.
Reset the short circuit between pin 3 and
pin 8 of J1 connector, or close the external
interlock signal.
FAULT: OVERTIME SX
Within each step of the soft start mode

minutes.
(X) is the step number from 0 to 9
indicating the step number not passed).
Verify that system has no leaks. Press the
