position, the jumper configures the relay to Normally-closed
operation.

Discrete Input Range Selection - Under the personality card are
two sets of three position jumpers labeled “DI1” and “DI2.” DI1
refers to discrete input No. 1 and DI2 to discrete input No. 2. In the
A-B position the input is set to trigger on 120V AC or DC. In the B-C
position the input is set to trigger on 24V AC or DC. These jumpers
must be moved in pairs for each individual relay, but each relay may
be setup differently.

Troubleshooting

If you experience problems with your system, check the following list
for some common solutions.

LCD blank and no system response - Check 24 VDC supply
polarity and capacity (>300 mA).

LCD Hard to view - In the C

ONFIGURE

menu adjust the contrast

for a better viewing angle.

LCD active, unit will not respond to position or control
commands, and the analog outputs do not change -
Check
to see if the unit is in Test mode by looking for a flashing “T” on
the right side of the display. The unit will be in Test mode any
time you are in the C

ALIBRATE

or C

ONFIGURE

menu. If you are in

the C

ALIBRATE

or C

ONFIGURE

menu, use the LAST OPTION key

to move up to the top of the menu and exit from Test mode. If
that does not clear the flashing “T” from the display, go to the
T

UNE

menu and use the mode command to put the system in

Auto or Manual mode. If the system displays a flashing “E” or
“A” on the left side of the display, check the cause of the error or
alarm using the ERR/ALRM option in the S

TATUS

menu. If the

Alarm is a trip condition, then you can view the cause of the trip
by setting the ROW1 variable to show Mode/Status in the
S

TATUS

menu.

System will not respond to discrete commands - Check
jumper selection to make sure the input is set to the proper
range and that the system is not in Test mode.

Pressure sensors appear to saturate prematurely - Check the
rating of the sensors in the system information option of the
S

TATUS

menu to verify the rating (the rating is also etched on the

sensor). Check the sensor gain (set in the C

ALIBRATE

menu) in

the P1 & P2 option (the standard range is 39 mV < out < 78
mV).

Stroke calibration aborts or hangs - Check the air supply and
make sure it is stable. A regulator may be required to stabilize
the air supply in some systems.
