Tyco Galaxy SC Controller User Manual

Tyco Electronics Galaxy SC Controller J85501F-1
Issue 13 February 2001 Feature Descriptions 7 - 40
SHVSD BOOST Controls the rectifier Internal high voltage shutdown
threshold in the Boost Mode. Should be set higher
than the plant HV BOOST.
LDSH Forced Load Share between rectifier’s Enable/
Disable.
RMOVE RECT Rectifier is configured when plugged to the
controller and the ID is set in the rectifier. This
configuration remains in memory even when the
rectifier is removed. This field allows the removal of
the rectifier from the controller’s memory.
Rectifier
Monitoring and
Control
The Galaxy SC monitors each rectifier calculating the rectifier current,
and present state. From the rectifier signals, the Galaxy SC determines
the rectifier state, which, listed in order of priorities, is either:
• VACANT, if the rectifier or rectifier cable is not attached to the
Galaxy SC.
• OFF, if the rectifier is attached to the Galaxy SC, but is turned off
from the rectifier front panel, the rectifier has lost power, or has
some internal failure.
• STANDBY, if the rectifier is attached to the Galaxy SC, is turned
on from the rectifier front panel; however the Galaxy SC has turned
the rectifier off and holds the rectifier in reserve.
• ON, if the rectifier is attached, is turned on and is operating
normally.
A rectifier state history records state changes for all the rectifiers in the
plant. In addition, rectifier alarms are placed in the system history log.
If any rectifier has an alarm, the rectifier state and particular alarm signal
will show the alarm status. The alarm is indicated only at the plant level.
So multiple simultaneous rectifier alarms of the same type can only be
diagnosed by monitoring the individual rectifier statuses or by
monitoring rectifier diagnostics. The alarm will be shown only once at
the plant alarm level.
Remote
Peripheral
Monitoring
Modules and
Channels
The Intelligent Galaxy SC supports a network of two-wire interface
smart modules called Remote Peripheral Monitoring. The network can
have up to 255 modules. The system supports the Voltage Module
(VTM), Shunt Module (SHM), Temperature Module (TPM), Binary
Module (BIM) and Control Relay Module (CRM). Following is a list of
all common features:
