SHOCK HAZARD
Troubleshooting, opening this equipment and removing any panels or covers will expose the
user to the risk of a shock hazard. There are no user serviceable parts inside this equipment.
Refer all servicing only to qualified service personnel.

Simultaneous IOP calibration

Recalibrate each HLAI IOP separately in an off-line HPM or follow the nonredundant High Level
Analog Input FTA calibration procedure in subsection "Nonredundant HLAI IOP Calibration Procedure"
( "IOP Calibration Procedures") to simultaneously calibrate both IOPs. The calibration voltage source
must be connected to both sets of calibration terminals on the redundant model FTA simultaneously with
parallel wiring as shown in Figure 217 for the model MU-TAIH12 FTA. Refer to the Process Manager
I/O Installation manual for the assembly layout and calibration terminal locations for all the HLAI FTA
models.
