Operator Control Panel (OCP)
(8236-341, 8236-361)
The Operator Control Panel includes functions typically used to start and stop a
turbine, and perform overspeed tests. The OCP includes a front access NEMA 4
enclosure and is provided with the switches and meter mounted within the
station’s front door. The Operator Control Station is suitable for use in Class I,
Division 2, Groups A, B, C, and D or non-hazardous locations only. Refer to
Chapter 1 of this volume for related installation and wiring warnings.
To complete the interface to the control, the OCP switches and meter must be
hardwired to the 5009 control and the control program configured to accept the
interface logic (Analog Output and Contact Inputs programmed).
Depending on the station’s purpose, not all the OCP switches may need to be
connected to the control (overspeed, etc.).
Wiring Notes:
Refer to Figure 8-3 for OCP wiring.
•
Wiring must be in accordance with Class I, Division 2 wiring methods and/or
in accordance with the authority having jurisdiction.
•
It is recommended that 0.75 mm² (20 AWG) or larger wire be used between
each device and termination module.
•
Shields should be connected to earth ground at all intermediate terminal
blocks, as well as terminated at the control terminal block. The exposed wire
length, beyond the shield, should be limited to 25 mm (1 inch).
•
Do not place shielded wires in the same cable conduit with high-voltage or
large-current-carrying cables.
Installation of the Operator Control Panel
Mount the control within 300 m (1000 ft) from the 5009 control, leaving an
adequate service loop.
1. Mark the panel location and mounting holes (see Figure 8-2).
2. Drill and tap the mounting holes using the appropriate size hardware.
3. Place the panel in position, insert the mounting screws into the tapped holes,
and tighten the hardware securely.
