Features Overview:
The 72G series of
elevator starters
consists of a Solid
State Starter and
Fault Contactor
The Solid State
Starter controls
the current during
the start and
provides overload,
current imbalance,
reverse phase,
single phase and
shorted SCR
protection. In
addition to those
faults, on power up
the starter will
check the motor
configuration.
Power wiring terminations
Liquid Crystal Display
Port for Infrared or
Serial Communication
Ground Screw
The Fault Contactor
provides a means for
interrupting current
during shorted SCR
conditions. It DOES
NOT provide
electrical isolation
when opened if wired
in delta.

setup and operation

Control Power Connections:
Terminal Customer Connections
A 120 VAC, 500VA supply should be connected
between the Line and Neutral terminals, points 1
and 3. This supply also powers the fault contactor.
Terminals 1 and 2 are internally connected. An
external jumper wire is required to connect
terminal 1 to terminal 9 to feed the NO Ready
contacts.
Figure 2: Control Power Connections
The customer control connections on the Solid
State Elevator Starter feature a removable terminal
block. The layout is shown to the left. All
terminations are screw type.

Terminal Customer Connections
The 120 VAC motor run signal is connected to terminal
4. The neutral of the motor run circuit must be
referenced to terminal 3, the neutral of the Control
Power input.
This output is used to either directly supply power to
the Up valves or supply a signal to a control board to
indicate the motor is up to speed. This output utilizes a
Triac rated for 120 VAC.
This contact may be used to signal a control board that
the unit is in a fault condition.
Terminal 9 should be connected via a jumper wire to
either terminal 1 or 2. This provides a hot feed to the
fault contactor coil when the NO Ready contact is
closed.
The terminals marked 10 and 11 are the switched side
of the NO Ready contact. This configuration allows
terminal 10 to be used to signal that the starter is ready
to run while terminals 11 and 12 (neutral for the fault
contactor coil) control the fault contactor.
Figure 2a: Control Power Connections
Note:
---Terminals 1 and 2 are tied together inside the unit as are terminals 3 and 12.
---The load on terminals 5 and 6 must not be greater than 1 amp at 120V. The load on
terminals 7 - 11 must not be greater than 3 amps at 120V. All terminals are rated for AC
voltages only.

Motor Connections:
Inside Delta Motor Wiring
The motor wiring should be connected exactly as shown in Figure 4. If it is not, the starter will
detect a motor wiring error. If you have elected to cycle the fault contactor on each start, you
must contact technical support for directions on configuring the starter and wiring in a required
off delay timer.
