Technical Data and Specifications
Reduced Voltage Starters
Edge and Level Sensing Control
Edge Sensing
Edge sensing requires
+24 Vdc power be
momentarily applied to
Control Terminal Block Pin 1
(with Terminal P at +24 Vdc)
to initiate a start under all
conditions. After a stop or
fault occurs, the +24 Vdc
must be removed, then
reapplied to Terminal Pin 1
before another start can
occur. This control
configuration should be used
when restarting of the motor
after a fault or stop must be
supervised manually or as a
part of a control scheme. The
cycling of +24 Vdc power to
Terminal 1 Pin before starting
is required regardless of the
position of the auto reset
switch on the DIM.
Level Sensing
Level sensing will enable a
motor to restart after a fault
is cleared without cycling
+24 Vdc power to Terminal
Pin 1 as long as:
●
Terminal Pin P is supplied
with +24 Vdc (to start
from Control Terminal
Block, Terminal Pin 3
must also be enabled)
●
The auto reset switch on
the DIM is set to enabled
●
All faults have been reset
This control configuration
should be used where it is
desirable to restart a motor
after a fault without additional
manual or automatic control.
An example of this condition
would be on a remote
pumping station where it is
desirable to automatically
restart a pump after a power
outage without operator
intervention.
Note: If the auto reset feature
is used, CAUTION must be
exercised to ensure that any
restart occurs in a safe manner.
