To conform to the EMC directive, a ferrite core is required on the input of the
starter module. Consult the factory for the recommended part number.
For a CE compliant installation, all electrical connections must be made by
a qualified electrician.

Terminal Description

V3 / V4

Wet Auto Input: Accepts wetted customer input.
Input voltage must be within 12 - 250 VAC/VDC
(4.2mA maximum). Sending voltage to the contact
will operate the starter when in Auto Mode.

V1 / V2

Fireman’s Override Input: Accepts wetted
customer input. Input voltage must be within
12 -250 VAC/VDC (4.2mA maximum). Sending
voltage to the contact will operate the Motor
Starter in all modes including OFF and Shutdown
Input. When active, all mode LED’s flash.

O1 / O /

O2

Status and Fault Relay Output
- O1 - Fault Terminal: Con nects to a relay contact
that closes in a fault condition.
O - Common: Common connection for the fault
and status relays.
O2 - Run Status: Connects to a relay contact
that closes when the motor draws 60% of the
FLA setting. See below for Relay Output current
ratings
110VDC, 0.3A Resistive
125VDC, 0.5A GP
30VDC, 2.0A Resistive
120VAC 50/60Hz, 0.5A Resistive
125VAC 50/60Hz, 1.0A GP
240VAC 50/60Hz, 0.25A Resistive

D5 / D6

Dry Shutdown Input: When the input is open
the Motor Starter will open in all modes (except
Fireman’s Override), HAND/OFF/AUTO LED’s will
flash indicating a shutdown. (N.C. dry contact or
transistorized input)

Terminal Description

D3 / D4

Dry Permissive Auto Input: N.O. dry contact
input. When the input is open, the Auto input is
disabled. 24VDC, 2.4mA maximum

D1 / D2

Dry Auto Input: N.O. dry contact or transistorized
input. When closed, the starter will operate when
automatic mode is selected. 24VDC, 2.4mA
maximum

A- / A+

Damper Control Output: 24VDC 1A maximum.
Provides a 24VDC damper control output when
the motor starter is commanded in either auto or
hand mode. The damper control output must be
wired with a damper end switch input as noted
below to prevent overloading of control circuit.

L- / L+

Damper Switch Input: N.O. open dry contact.
Switch input dry contacts must be rated for at
least 24VDC, (2.4mA maximum). When used with
the damper motor output, the contactor coil is in
series with customer provided damper contacts
which disable the motor starter until the damper is
in position.

C- / C+

Contactor Output: Provides a 24V output to the
contactor when the motor starter is commanded
in either Hand or Auto mode and the damper
switch input is closed. (Wired from manufacturer).
24V, 0.42A Max. for a Franklin Control Systems
contactor with 24VAC coil.
