You can monitor your unit with a system (user-supplied) controller or a Windows-
based personal computer running Thyro-Tool Pro software. To order this software,

SETPOINT CONTROL

The setpoint control characteristic of the Thyro-PX DC power controller is easily
adapted for the control output signal of the upstream process controller or automation
system. All typical control voltage and control current signals can be used. Inverted
operation (ending value is smaller than the starting value in voltage or current) is also
supported.
The effective setpoint is the total setpoint. It is formed by adding the three setpoints
as shown in
Analog setpoint
Bus setpoint
Motor potentiometer
Analog setpoint
Bus setpoint
Motor potentiometer
Figure 5‑7. Total setpoint
The local analog setpoint, and local motor potentiometer setpoint are used by default.
If an Anybus module is installed, the remote bus setpoint is used by default.
Switching between the local setpoint and the remote setpoint can be controlled using
the Thyro‑Touch display, the Thyro-Tool Pro software, or the bus communication. A
digital I/O line may also be configured to control the local/remote switch.
