Step
What to do
1
Make sure the
controller is configured
for Time/Current or
Current/Time
Proportional output.
2
Check the field wiring.
3
Check the relay output. Put the controller into Manual mode. Vary the output
4
Check the Current
Proportional Output.
5
Recalibrate the
controller.
6
Change MCU and/or
Current Output boards.
How to do it
Change relay.
Installation instructions supplied with the new
board.
How to do it
Make Output Set Up group function prompt Output
Algorithms = Time Current or Current Time.
See Output Set Up Group for more information.
Make sure the NO or NC contact wiring selection is
correct.
See Installation for more information.
above and below the present value. Observe OUT1
indicator on the operator interface. Listen for a click
from the relay when the OUT1 indicator changes
state.
Put the controller into Manual mode and change the
output from 0 % to 100 % (4-20 mA). Use a DC
milliammeter at the rear terminals to verify the output.
See Output Calibration for more information.
