Encoder Installation

(PC-8e only)

1. Connect up to two encoders to monitor line speed.
NOTE: Line 1 and line 2 on the ADM.
NOTE: Encoder type must be quadrature differential
line driver (RS422). Scaling is entered in the
encoder setup screen using the live calibration fea-
ture.
NOTE: Some encoders have Z and Z' connections.
These are not used and do not need to be con-
nected.
NOTE: Encoder direction can be reversed by swap-
ping A and A' with B and B'. Do this is the line speed
reads negative on the ADM.

regulators to vary pump pressure based on line
speed. Hardware automatically detects whether an
I2P or V2P is connected.
NOTE: Pressure vs. line speed settings are entered
on the run-up setup screen. See Run Up Control,
