Motor Control Diagnostic Codes
312063Z 11
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.
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 .
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 .
E21: No component A
transducer
1. Check transducer A connection at J3 on motor
control board, F
IG. 5, page 32, and clean contacts.
2. Reverse A and B transducer connections. If error
moves to transducer B (E22), replace transducer A,
Transducers, page 33. If error does not move,
replace motor control board, Motor Control Board,
page 31.
E22: No component B
transducer
1. Check transducer B connection at J8 on motor
control board, F
IG. 5, page 32, and clean contacts.
2. Reverse A and B transducer connections. If error
moves to transducer A (E21), replace transducer B,
Transducers, page 33. If error does not move,
replace motor control board, Motor Control Board,
page 31.
E23: High fluid pressure
1. Relieve pressure. Verify low pressure with analog
gauges. Turn main power OFF then ON
. If error persists, do checks below.
2. If pressure imbalance is set to Warning instead of
Alarm (see page 31), an E23 will occur. See E24:
Pressure imbalance for causes and checks.
E24: Pressure imbalance
NOTE: Upon initial start-up this diagnostic code will not
cause an alarm for 2 minutes.
NOTE: If the pressure difference between components
A and B exceeds 500 psi (3.5 MPa, 35 bar), an E24 will
occur. This default value is adjustable; see the operation
manual.
