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 CONFIGURE menu. If you are in

the C

ALIBRATE or CONFIGURE 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

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

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

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.
