Operator Interfaces
In order to confi gure and program the Orion System controllers, you
must have an Operator’s Interface or a personal computer with the Prism
II computer front-end software installed. Three different Operator Inter-
faces are available for programming of the Orion Controls System—the
Modular Service Tool SD, the Modular System Manager, and/or the
System Manager TS II. These devices allow you to access the status and
setpoints of the controllers on your communications loop. This manual
describes the Modular Service Tool SD. If using the Modular System
Manager or System Manager TS II, please see the Operator Interfaces
Technical Guide or the System Manager TS II Technical Guide. If using
Prism II, please see the Prism II Technical Guide.
The Modular Service Tool allows you to view any input or output status
and change any setpoint to fi ne-tune the operations of the total system.
All keypad operations are simple and straightforward, utilizing non-
cryptic plain English messages.
