Graco Reactor E-20 AH9030 [18/76] E32 motor control overtemperature
Communication Diagnostic Codes
18 312066ZAF
E32: Motor Control
Overtemperature
The E32 error code indicates a high temperature
condition within the motor control board (701). This
could be caused by an abnormally high ambient
temperature in the work location, blockage of cooling
vents in the cabinet, or the failure of the cooling fan
inside the cabinet.
1. Perform the Pressure Relief Procedure, page 25.
Verify low pressure with analog gauges.
2. Turn main power OFF then ON .
If error still remains, identify cause of the
overtemperature condition and remedy.
Communication Diagnostic Codes
E30: Momentary loss of
communication
Communications between the display and the motor
control board or the temperature control board have
been momentarily lost. Normally, when communication
is lost, the corresponding display will show E99. The
corresponding control board will register E30 (The red
LED will flash 30 times). If communications are
reconnected, the display can show the E30 for a short
time (no more than about two seconds). It should not be
possible for E30 to be shown continuously, unless there
is a loose connection causing the display and the board
to continuously lose and regain communication.
Check all wiring between the display and the
corresponding control board.
E99: Loss of communication
Communications between the display and the motor
control board or the temperature control board has been
lost. When communication is lost, the corresponding
display will show E99.
1. Check all wiring between the display and the
corresponding control board. Pay close attention to
the wire crimping on plug J13 for each board.
2. Measure the incoming voltage to the board (it
should be ~ 230Vac).
3. If it was only receiving 1 leg of the 230Vac the board
may light up, and still not function properly. Correct
the incoming voltage problem.
Step 2 measures line voltage and should be done by a
qualified electrician. If work is not performed properly
it may cause electric shock or other serious injury.
