Galaxy Power System Verification Procedures
Issue 3 January 2008 Galaxy Millennium Controller Performance Verification Procedures 3 - 15
Modem/Data
Switch
If the Modem (L-AE) and/or Data Switch (L-AH) options have been
provided, they can be tested after wiring and configuration is completed
by dialing into the modem port and, if equipped, passing through to the
devices wired to the equipped Data Switch ports. Refer to the controller
product manual for T1.317 Data Switch commands.
Note: If the controller is regularly accessed using a modem, from a
remote monitoring station, this test may not be necessary.
Remote
Peripheral
Monitoring
If J85501G-1 Remote Peripheral Monitoring units have been equipped,
each channel configured may be tested for accuracy with a clamp-on
ammeter (for Shunt Monitor channels), voltmeter (for Voltage Monitor
channels), or thermometer (for Temperature channels). If alarms have
been configured through the use of User Defined channels, they may
also be tested by adjusting their program line to move the thresholds or
by adjusting the channel programming to change the value reported for
the channel.
Once set, it is not recommended to change these UDE program lines,
unless it is attempted by a qualified and skilled professional. Refer to the
product manual if it is required to make any adjustments/changes to the
RPM modules or UDE.
Rectifier
Sequencing
If Rectifier Sequencing in an intelligent controller has been enabled (via
EasyView path: MAIN
→ CONFIGURE → RECTIFIERS), testing can
be completed by temporarily using a shorting clip across BSL2 Alarm
Interface positions 75-76 (ETR/ETRR) This will cause all rectifiers
configured for Rectifier Sequencing control to shut Off. Releasing this
clip will then cause the rectifiers to restart sequentially in the manner in
which they have been programmed.
