Name and Description
Code
Major Fault or Power-up or Power Off
The module is just powering up and not
initialized yet or there is a major
OFF
hardware fault causing the module to be
held in reset by the controller. LED
control is not possible for this condition
and will remain off.
Calibration invalid or corrupted
This code will be seen for newly
3
manufactured boards that have yet to be
calibrated.
Serial Number Invalid or Corrupted
This code will only be seen if the
4
module has been calibrated but the serial
number is not programmed, or the flash
memory sector is corrupted.
Analog Communications Error – Input
A communications error or connection
5
error took place between the MCU and
ADC or PGA circuitry.

Module Operation
WARNING
The 2085sc-OF8 module is expected to operate indefinitely. It does not require
periodic maintenance or calibration. The 24 VDC field power supply must be
present to allow for outputs from the module channels.
Hazard of damage to module.
When multiple channels are configured in voltage mode, and an external
24 V power source is applied to the channels via the terminal block, there
is the possibility that the module will be damaged if multiple channels
simultaneously experience over voltage conditions.
This is because the heating caused by the overvoltage condition will apply
to a very small area and may result in damage to that area.
The module communicates to the controller through the bus interface. The
module also receives 5 and 24 VDC through the bus interface.
