E30: Momentary loss of
communication
If communication is lost between the display and the
motor control board, the display will normally show E99.
The motor control board will register E30 (the red LED
will blink 30 times). When communications are
reconnected, the display may show E30 briefly (no more
than 2 seconds). If the display shows E30 continuously,
there is a loose connection causing the display and
board to repeatedly lose and regain communication.
E31: Pumpline reversing switch
failure/high cycle rate
Failure of a pumpline switch or switch mechanism may
result in a high cycle rate, causing an E31 to occur.
Replace the switch or switch mechanism. See
E31 may also occur if the system is modified to produce
a higher flow rate.
E99: Loss of communication
If communication is lost between the motor control
display and the motor control board, or the temperature
control display and the temperature control module, the
affected display will show E99.
1. Check all wiring between the display and the motor
control board and the temperature control module.
Pay close attention to the wire crimping at J13 on
the motor control board (page 32) and (C) on the
temperature control module (page 34). Unplug and
re-plug connectors.
2. Incoming voltage should be 230 Vac. Check the
temperature control module voltage at terminal
block (805) on the circuit breaker module (see page
66). Check the motor control board voltage at
motor/pumps circuit breaker (813), see page 29.
Check if temperature control module or motor
control board is causing error:
3. Swap display connection on temperature control
module (C) with display connection on motor control
board (J13).
4. If error no longer occurs, the board or module was
at fault. Switch connections back to ensure
connector was not poorly connected.
