VI.
DISPLAY- “Control supply fail”
TROUBLESHOOTING:
a.
Check whether Fuse-F3 is blown; If yes, replace with good fuse of 150mA, 250V
rating.
b.
With the help of multimeter measure the Control Supply Voltage (AC voltage
between Orange and Black wires of J2 on Power Supply card), which is to be
220VAC/110VAC as per the customer requirement. If voltage is still not coming then,
check the Molex connector between fuse plate and transformer.
c.
If the requisite voltage is measured; but display continue to show the same error
message then replace the Power Supply Card. But if the requisite voltage is not
measured then, the fault could be with transformer. Replace with new transformer
and check again.
VII.
DISPLAY- “Jammed Valve”
TROUBLESHOOTING:
a.
The Jammed valve condition has to be released manually.
VIII.
Motor running in wrong direction
Whenever there is a replacement of Motor then there is a possibility of occurrence of
this error i.e. the actuator will run in wrong direction for the respective command inputs
(actuator runs in open direction for close command and vice versa). To troubleshoot this,
interchange any 2 wires of the motor when the Motor is replaced.
IX.
In case if Remote-Local mode selection option from REMOTE is not happening
(optional feature); check for the wiring at the customer end according to the WD.
X.
In case of actuator running inadvertently (with ‘ESD’ message on LCD) either in OPEN
or CLOSE direction depending on the software configuration, check if ESD is activated
(wiring mistake) using the WD provided.
XI.
In case the actuator is not taking command in any particular direction check if INHIBIT
feature is enabled (wiring mistake) using the WD provided.
XII.
In case the motor is not responding to the OPEN & CLOSE command and
OPENING/CLOSING is indicated on LCD:
Check if J3 of Power Supply card is plugged properly. Check the requisite voltages
(110/230V) at the contactor terminals (K, K1 & K, K2 –refer Fig. E below).
a)
If the voltages are proper then, it could be the failure of the contactor; Replace the
contactor.
