time delay is set to a time value, which is greater than the typical time that the
transfer mechanism typically takes to operate from one supply position to the
neutral position. When the TSC 80e controller is supplied from the factory with
a Thomson Technology transfer mechanism the Neutral Position Delay will be
factory set for correct operation.
4.6.9.7.Pre-Transfer Delay
The pre-transfer delay period will be initiated upon an impending transfer in
either direction from a powered-to-powered source. The pre-transfer output
relay will momentarily energize (as per the pre-transfer time setting) prior to a
load transfer and will stay energized until the post-transfer delay time
commences. Select desired pre-delay time in seconds. The range of settings
is 0 to 60 seconds. If no delay is required, set this time delay to zero.
4.6.9.8.Post-Transfer Delay
The post-transfer delay period will be initiated on expiry of the pre-transfer
delay (overlapping) in either direction. The post-transfer output relays will
energize (as per the post-transfer time setting) after the load transfer and will
stay energized until the post-transfer delay time period expires. Select desired
post-delay time in seconds. The range of settings is 0 to 60 seconds. If no
delay is required, set this time delay to zero.
4.6.10.PROGRAMMABLE OUTPUTS
The TSC 80e transfer controller provides programmable output relay functions.
signals. Each output can be assigned one of the following programmable functions.
The output relay energizes when one of the following conditions occurs. NOTE: Only
one function may be programmed.
LOAD ON UTIL Contacts change state when the utility transfer
power-switching device is closed and load
voltage is present.
XFER TO UTIL Contacts change state when the controller
signals a transfer to the utility position.
LOAD ON GEN Contacts change state when the generator
transfer power-switching device is closed and
load voltage is present.
