General Information
24 Vdc Control Power—Terminal Block Connections
●
Run Enable 24 Vdc applied to Terminal “P”, This 24 Vdc
input must be maintained continuously during RUN
operation from either the terminal block or a network.
●
START Command enable from Terminal Block Voltage
applied to terminal “3” of the control power terminal block.
When a 120 Vac signal is applied to the Comms Select
terminal, START control from the terminal block will not be
recognized.
●
START Command with 24 Vdc applied to Terminal “P”,
apply 24 Vdc to Terminal “1” The signal requirement is
momentary, but maintained is acceptable. Terminals “P”
and “1” may be tied together for 2-wire control START/
STOP commands.
●
STOP Command Remove 24 Vdc from Terminal “P”.
Terminals “P” and “1” may be tied together for 2-wire
control START/STOP commands.
●
Wire size, minimum—14 AWG to all Terminal Block
connections. Wire should have no stands missing or
damaged during wire stripping. The use of terminal
ferrules is recommended to maintain connection integrity.
●
Control Power Supply Requirements.
●
Must meet or exceed steady state and inrush capacity
requirements.
– Steady State (sealed) = 25 Watts, 24 Vdc.
– Outrush = 240Watts, 24 Vdc for 150 ms minimum.
– Minimum supply voltage 24 Vdc measured at the
Terminal Block.
– Maximum allowable voltage drop measured at the
Terminal Block = 5 Vac.
Fault Reset Details
●
If the Status led is RED, the soft starter is in a fault
condition and will not recognize a START command. If a
reset attempt is unsuccessful, the fault is still present and
must be corrected.
●
If the soft starter appear s to have “tripped”, but the Status
LED is GREEN and there is no new Fault code in memory,
verify that the soft starter has not stopped due to a STOP
command.
●
Terminal “P” (permissive) must be energized (maintained)
to enable operation, but will not prevent a fault from being
reset. The Status LED can be GREEN without a signal at
the “P” terminal.
●
Terminal “1” is energized (momentary or maintained) to
issue a START command. Signal duration must be a
minimum of 500ms for the Soft Starter to recognize the
START command.
●
Terminal “P” is de-energized to issue a STOP command.
●
LEVEL Sense
●
Most commonly used Start Control parameter setting
●
Maintained Terminal “1” energized:
– START command is present when Terminal “P” is
energized (maintained).
– START command is present when any fault clears and
is then RESET.
RESET function may be either AUTO or MANUAL.
●
IMPORTANT NOTE: If the LEVEL sense parameter AND
the AUTO RESET parameters are selected, a motor
START command will exist if a 24 Vdc signal is present
on Terminal “P” and Terminal “1 and remains energized
when the fault condition clears. After a transient fault,
this condition may cause the motor to start
unexpectedly.
●
Momentary Terminal “1” energized:
– START command is present when Terminal “P” is
energized (maintained).
– START command is not present when any fault clears
and is then RESET.
– Terminal “1” must be again energized to issue a
START command.
●
EDGE Sense
●
Maintained Terminal “1” energized:
– After a fault has been RESET the 24 Vdc signal must
be removed from the Terminal “1” to enable a START
command. After a fault has been RESET, re-energizing
Terminal “1” (maintained or momentary) will issue a
START command.
●
Momentary Terminal “1” energized:
– If Terminal “1” is energized (momentary) by the soft
starter control system, the START signal must be
reapplied after the RESET has been accomplished.
●
In either case above, Terminal “1” must be de-energized
momentarily if the RESET parameter is in either
MANUAL or AUTO to enable a START command.
●
Thermal Overload
●
After an Overload trip—no restart is allowed until the
prescribed time period has elapsed.
●
Trip Rest Time Periods
– 1st Trip = 3 minute RESET inhibit.
– 2nd Trip (within 48 minutes of 1st Trip) = 6 minute
RESET inhibit.
96 minutes to restore 3 minute inhibit level.
– 3rd Trip (within 48 minutes of 2nd Trip) = 9 minute
RESET inhibit.
144 minutes to restore 6 minute inhibit level.
240 minutes to restore 3 minute inhibit level.
– Cycling 24 Vdc control power does not reset the
inhibit times.
