Section 3. Accessories
3.1 Programmed Transition
NOTE
ATSs using microprocessor logic control do not use this
section. The programmed transition function takes
place within the microprocessor and no time relays are
required. See TP-5664, operation and installation
manual for the M340+ controller, for operational details.
Relays K3 and K4 on the interface board are replaced
with a standard form C relay.
3.1.1
Description
The Programmed Transition accessory consists of two
timing relays that plug into an interface circuit board.
See Figure 3-1. If these relays are present, power
transfers from normal to emergency or emergency to
normal in three steps: (1) the switch or circuit breaker for
the previously connected power source opens, (2) a
delay period, adjustable from 2 to 40 seconds, allows
any residual voltage in the load circuit to decay, and (3)
the switch or circuit breaker for the new power source
closes.
3.1.2
Adjustment
Two separate timing relays are used. One relay,
K4 (TDOE), produces the time delay for the normal to
emergency power transfer. The other relay, K3 (TDON),
produces the time delay for the emergency to normal
power transfer. Each relay has a separate adjustment.
To make the adjustment, proceed as follows.
Accidental starting.
Can cause severe injury or death.
Disconnect battery cables before
working on generator set. (Remove
negative
(--)
lead
first
when
disconnecting battery.
Reconnect
negative
(--)
lead
last
when
reconnecting battery.)
WARNING
Disabling the generator set. Accidental starting can
cause severe injury or death.
Before working on the
generator set or connected equipment, disable the generator
set as follows: 1) Move the generator set master switch to the
OFF position. 2) Disconnect power to the battery charger.
3) Remove battery cables, negative (--) lead first. Reconnect
negative (--) lead last when reconnecting battery. Follow these
precautions to prevent starting of generator set by an
automatic transfer switch, remote start/stop switch, or engine
start command from a remote computer.
Hazardous voltage.
Can cause severe injury or death.
Disconnect all power sources before
opening enclosure.
(under 600 Volt)
WARNING
Hazardous voltage.
Will cause severe injury or death.
Disconnect all power sources before
opening enclosure.
(600 Volt and above)
DANGER
Hazardous voltage.
Can cause severe injury or death.
Disconnect power sources before
servicing.
Install barrier after
adjustments,
maintenance,
or
service.
(under 600 Volt)
