3-4-3 Wiring Other Terminals

The Power Supply Units provide a START input and a RUN output. These termi-

nals can be used to help control system operation.

START input (CPU Racks only)

24 V,10 mA

RUN output (all Racks)

Maximum Switching Capacity:

250 VAC: 2 A (resistive load, cos

f = 1)

250 VAC: 0.5 A (inductive load, cos

f = 0.4)

24 VDC: 2 A

Note

1. Use reinforced insulation or double insulation on the DC power supply con-

nected to CV500-PS211 Power Supply Unit when complying with EC direc-

tives (low voltage).

2. The maximum switching capacity of the CV500-PS211 Power Supply Unit is

2 A at 24 VDC when complying with EC Directives (low-voltage directives).

START Input

The START input terminals are short-circuited at the factory with a short bar. The

short bar can be removed and the terminals wired to a 10-mA, 24-VDC external

input to control PC operation. When these terminals are open, PC operation will

stop.

RUN Output

The RUN output terminals will be ON (closed) when the PC is operating in RUN

or MONITOR mode. These terminals can thus be wired to provide an external

signal indicating the operating status of the PC, such as is used in the emergen-

cy stop circuit in the next section.
