4. COMPONENT DESCRIPTION AND
SPECIFICATION
This Section provides descriptions and specifications for the RMC Power Supply, the T161
Series Controllers, the B81318-001 Hand Held Terminal, the Encoder Simulator Option
Card, and the 300A Series Motors.
4.1. Power Supply Description, Specifications
The power supply has the following features:
• Single or Three Phase A-C Operation
• Direct off-line 220 VAC Operation
• Soft Start (A-C Inrush Current Limiting)
• Integral Shunt Regulator
• Fast Bus Discharge
• Phase Loss Detection
• Provision for External Regen Resistor
• Regen Electronic Circuit Breaker
• Power Supply Fault Relay
• Diagnostic LED's
The major components of the power supply are indicated in Figure 4-1.
WARNING
Power supplies contain large capacitors that maintain high voltage on the
DC+ to DC- terminals for several minutes after input power is removed if the
regen resistor circuit is open (fuse blown or wiring open).
Wait at least 5 minutes after power shutdown for capacitors to discharge.
Using a multimeter, measure the DC BUS (at X7 Pin #1 and #2) to ensure
that it has been discharged. Failure to follow this procedure might result in
serious personal injury.
4.1.1. Diagnostic LED's
The status of the power supply may be monitored using the diagnostic LED indicators on
the front panel as listed in Table 4-1.
