Troubleshooting Tips

Symptom

Check/Action

No display at all

Check power at power connector

Not able to change setup or

programming,

Locd

is displayed

Meter is password-protected, enter

correct six-digit password to unlock

Meter displays error message

during calibration (

Error

)

Check:

Signal

connections

Input selected in

Setup

Minimum input span requirements

Meter displays

-99999

Check:

Input selected in

Setup

Corresponding signal at Signal

connector

Display is unstable

Check:

Input signal stability and value

Display scaling vs. input signal

Filter and bypass values (increase)

Display response is too slow

Check filter and bypass values

Display reading is not accurate

Check:

Signal input conditioner selected:

Linear, square root, etc.

Scaling or calibration

Display does not respond to input

changes, reading a fixed number

Check:

Display assignment, it might be

displaying max, min, or set point.

Display alternates between

and a number

Press Menu to exit max/min display

readings.

Relay operation is reversed

Check:

Fail-safe

Setup

Wiring of relay contacts

Relay and status LED do not

respond to signal

Check:

Relay action in

Setup

Set and reset points

Flashing relay status LEDs

Relays in manual control mode or relay

interlock switches opened.

Meter not communicating with

application programs

Check:

Serial adapter and cable

Serial

settings

Meter address and baud rate

If the display locks up or the meter

does not respond at all

Cycle the power to reboot the

microprocessor.

Other symptoms not described

above

Call Technical Support for

assistance.

Note: Certain sequences of events can cause unexpected results. To
solve these issues, it is best to start fresh from factory defaults and map
changes ahead of time, rather than at random.
