4.2.5. ENGINE WARMUP DELAY
A potentiometer is provided to adjust the TSC 80’s Engine Warm-up Delay timer. A
transfer to the generator supply will be initiated when the voltage and frequency are
within limits and upon expiry of the Engine Warm-up delay timer. The range of setting
is 0 to 60 seconds. If no delay is required, set this time delay to zero.
Refer to Table 1 for the factory default settings of the Engine Warm-up Delay timer.
4.2.6. ENGINE COOLDOWN DELAY
A potentiometer is provided to adjust the TSC 80’s Engine Cooldown Delay timer. The.
Engine Cooldown period will be initiated once the load has transferred from the
generator supply. The engine start signal will be maintained until expiry of the
cooldown delay timer. The range of setting is 0 to 30 minutes. If no delay is required,
set this time delay to zero.
Refer to Table 1 for the factory default settings of the Engine Cooldown Delay timer.
4.2.7. UTILITY RETURN DELAY
A potentiometer is provided to adjust the TSC 80’s Utility Return Delay timer. The
Utility Return delay period will be initiated once the utility supply has returned within
limits following a utility power failure condition. The range of settings is 0 to 30
minutes. If no delay is required, set this time delay to zero.
NOTE
The utility return delay will be bypassed should the generator
fail during the time delay period.
Refer to Table 1 for the factory default settings of the Utility Return Delay timer.
4.2.8. NEUTRAL DELAY
A potentiometer is provided to adjust the TSC 80’s Neutral Delay timer. The neutral
delay time period will be initiated once the load bus voltage drops below the dead-bus
threshold value when both of the supply power switching devices are open during a
transfer sequence. Select desired neutral delay time in seconds. The range of
settings is 0 to 60 seconds. If no delay is required, set this time delay to zero.
NOTE
The neutral delay will be bypassed should the operating power
fail for longer than the timer setting.
Refer to Table 1 for the factory default settings of the Neutral Delay timer.
