Motor Control Diagnostic Codes

Motor control diagnostic codes E21 through E27 appear on pressure display.

There are two types of motor control codes: alarms and warnings. Alarms take priority over warnings.

See repair manual for corrective action.

Alarms

Alarms turn off Reactor. Turn main power OFF

then ON

to clear.

NOTE:

Alarms can also be cleared, except for code 23, by

pressing .

NOTE:

Code 24 (pressure imbalance) is set to an alarm default of 500 psi (3.5 MPa, 35 bar). To change to a warning, see Reactor Repair-Parts manual 313540. To change the default pressure imbalance setting, see page 27.

Diagnostic Codes

Warnings

Reactor will continue to run. Press to clear. A

warning will not recur for a predetermined amount of time (varies for different warnings), or until main power

	is turned OFF		then ON	.
