TIME MARK 153 - Page 40

INSTALLATION
Connect the 3-phase power to the terminals marked A,
B, and C.
Connect the control circuit wiring to one set of the
output terminals.
(Optional) Connect the second set of output terminals
to an alarm circuit, or to the control circuit of a second
load.
A standard wiring diagram is shown in the TYPICAL
APPLICATION drawing. The contact markings are
shown in the TRIPPED, or Power-OFF condition.
FOR MANUAL RESET, instead of the built-in automatic
reset, install a normally-closed pushbutton switch
across the terminals marked RESET. The manual reset
leads should be kept as short as possible.
ADJUSTMENT
NOTE: When adjusting the Model 2652, you may
want to jumper the control circuit contacts, and
disconnect the alarm contacts connection, to
prevent the unit from cycling the load, during set-
up.
Turn the VOLTAGE ADJUST, RESET DELAY, and the
TRIP DELAY pots fully counter-clockwise.
Turn the VOLTAGE ADJUST clockwise, until the unit
trips (NORMAL indicator OFF; TRIP indicator ON).
Slowly turn the VOLTAGE ADJUST counter-clockwise
until the unit resets (TRIP indicator OFF).
Set the TRIP DELAY and RESET DELAY to the desired
time settings.
This trip level adjustment will be correct for most
applications.
The TRIP DELAY should help prevent nuisance tripping
due to power flucuations, or motor start-ups. Should
nuisance tripping still occur, increase the delay time a
little, or turn the VOLTAGE ADJUST slightly farther
counter-clockwise.
