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 the T1.317 Data Switch commands required.
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 the Remote Peripheral Monitoring option (L-AG) and J85501G1
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 Event (UDE), 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. Refer to the
Remote Peripheral Monitoring System product manual for complete
feature descriptions of each of these optional monitoring devices.
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 TB3 positions
12-13 (ETR/ETRR) on BJT board of the rear access SC controller
(Figure 2-2) and the BLG board of the front access SC controller (Figure
2-4). 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.
