DESCRIPTION
The diagnostic program
detects some malfunction in
the electronics controlling
the actuator.
The checksum of the EEPROM
memory that contains the
configuration data is wrong.
The communication
between Interface card and
motherboard card is lost.
Motor thermostat open for
high temperature in the
motor windings.
The test routine reports a
failure of contactor (coil or
auxiliary contact).
The valve does not move in
presence of an open or
close control.
No position change after
receiving an open or
close control.
Measured torque greater than
the relevant value configured
in torque setup or stroke
limits routine.
The voltage of the lithium
battery is too low (only
detected if the lithium
battery is present and the
relevant parameter of the
miscellaneous routine is set to
"present").
The position is > 4% after
ESD action.
Time needed to change the
position of the PST TRAVEL by
x
the spring action out
of specification.
Time to return to position
x before testing out of
specification.

RECOMMENDED ACTION
Some circuit is damaged and
does not work (Call Bettis
After-sales service to solve
the problem).
Reconfigure all parameters
(See details next page).
Check the main power supply,
or replace the Hardware
(Base card and Interface card).
Wait until the motor
cools down.
Check the contactor.
Check status of actuator
and valve mechanical parts.
Recalibrate both stroke limits.
Check status of actuator and
valve mechanical parts.
Operate the actuator in
opposite direction. Check the
torque needed to operate
the valve.
Change lithium battery.
Check reset time,
check electrical stroke limits,
check mechanical stops.
Check baseline values and
parameter T-PST.
Check baseline values and
parameter T-RET.
