FloBoss 107 Instruction Manual
7-18 Troubleshooting Revised June-2017
7.4.13 Troubleshooting AI/DI
This module provides eight AI or DI signals. Troubleshooting depends on
whether you have selected AI or DI wiring.
Required
Equipment

Multimeter

Digitial voltmeter

PC running ROCLINK 800 software
Caution
Failure to exercise proper electrostatic discharge precautions, such
as wearing a grounded wrist strap may reset the processor or
damage electronic components, resulting in interrupted operations.
As AI 1. Remove the module from service.
2.
Using a digital voltmeter, measure the “Loop” connector to “Gnd”
connector. It should measure 24 V dc.
3. Put a known 1-5 V dc from the input to Gnd on any AI-configured
channel and monitor the voltage in ROCLINK 800.
As DI 1. Remove the module from service.
2.
Short the DI+ to DI- and monitor the on/off toggling in ROCLINK
800.
7.4.14 Troubleshooting the Discrete Output Relay (DOR)
Required
