Diagnostic Codes

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 the motor and heat zones. Turn

main power OFF

then ON

to

clear.

Alarms can also be cleared, except for

code 23, by pressing .

Code 24 (pressure imbalance) is set to an alarm default of 500 psi (3.5 MPa, 35 bar). To change to a warning, see Reac- tor Repair-Parts manual 312063. To change the default pressure imbalance setting, see page 33.

Warnings

Reactor will continue to run. Press to

clear. A warning will not recur for a predeter- mined amount of time (varies for different warnings), or until main power is turned OFF

	then ON	.
