Output Calibration & Input Testing:
The outputs on the RCI-800 are factory calibrated and should not
require any adjustments.
To check the calibration of the outputs and relays
use jumpers H1-7 & H1-8 as shown below to set them to known states. If an
output should require some adjustment, the main circuit board has to be
removed from the analog input/output board to gain access to the output
calibration potentiometers.
With the power off
, remove the main circuit
board and set it aside leaving it connected to the analog input/output board
via the 4-conductor I/O cable. Turn the power on and insert jumper H1-8 on
the main circuit board and turn the OUTPUT CALIB. trim pot for a particular
output until that output reads 20mA. Turn the power off again before re-
assembling the unit.
If both jumpers are IN the analog and contact inputs are passed straight through to the analog and
relay outputs. This may help in troubleshooting input and output signals.
Make sure both jumpers are removed before resuming normal operation.
