Tyco Galaxy SC Controller User Manual

Tyco Electronics Galaxy SC Controller J85501F-1
Issue 13 February 2001 Feature Descriptions 7 - 36
Rectifier Restart The operator at any security level and at any time can manually restart
all rectifiers from the front panel or from the T1.317 interface.
In addition to the operator manually restarting rectifiers, auto restart of
rectifiers after an RFA can be enabled with a hardware and software DIP
switch.
Remote Rectifier
Turn On
A hardware and software DIP switch regulates the control of turning
rectifiers on remotely. When logged in via the T1.317 interface, at any
security level, the operator can remotely turn a rectifier on, if the
hardware and software DIP switches for remote turn on are enabled.
Remote Rectifier
Turn Off
A hardware and software DIP switch regulates the control of placing the
rectifiers in standby mode. When logged in via the T1.317 interface, the
super-user or administrator can remotely place a rectifier in the standby
mode, if the hardware and software DIP switches for remote turn off are
enabled.
Overriding
Rectifier Standby
Conditions
There are two conditions when rectifiers in standby mode will
abnormally be turned on: when there is low plant voltage condition and
when engine signals are invalid.
Low Plant Voltage
Conditions
Two plant voltage thresholds override standby conditions. These
voltage thresholds are the Battery On Discharge (BD) alarm threshold,
and a second threshold, known as the Rectifier On Threshold (ROT).
When the plant voltage drops below these thresholds, rectifiers are
turned on from standby mode, in hopes of maintaining normal operation
of the plant.
After the occurrence of a battery on discharge alarm, all rectifiers placed
in standby mode by the presence of the phase alarm, or by the energy
management algorithm, will turn on. Phase alarm and energy
management standby conditions are re-enabled after the battery on
discharge alarm retires.
During the initial portion of a battery discharge, plant voltage may drop
sharply by several volts, then rises soon after. This voltage drop is
known as the Coup De Fouet portion of the battery discharge.
Depending upon plant load conditions, this voltage drop may even be
below the Rectifier On Threshold. To account for the Coup De Fouet
voltage drop, the plant voltage must be below the Rectifier On
Threshold for a user programmable time threshold. This time threshold
