Maintenance and Troubleshooting
Opto22 Problems
4-14 Micro-Tech 9101/9201 Reference Manual, Rev J Thermo Fisher Scientific
This topic helps you solve problems with the Opto22 output and input
modules. The digital outputs (J7) can be either AC or DC or a
combination of both. Please note that the proper voltage Opto22 must be
used. AC source voltage requires an AC Opto22 module, and a DC
source requires a DC Opto22 module. The digital outputs are controlled
by the Micro-Tech. The LED indicator on the Opto22 module indicates
what the integrator is forcing—that is, Off (the LED is off) or On (the
LED is on).
Here is the procedure to force a digital output.
1. From the Run screen, press the Menu button three times to navigate
to the “Main Menu 3” screen.
2. Press the Test button, then press the down-arrow button until the
Digital Output Test screen appears.
