4.2.2 Three-Wire Control Connection
For standard 3-wire control, connect dry (voltage free) contacts for the
PTC OPTO
Stop / Start buttons as shown on the diagram directly above the terminal
strip. Connect the NO contact of the Start button to Terminal 1 (far left
terminal), the common point between the Stop and Start to Terminal 2
nd
(2 from left) and the NC from the Stop button to Terminal 3 (3
left).

4.2.2.a
The TE Series uses an internally pre-wired "seal-in" contact around
the Start button (Terminals 1 and 2). No external relay or auxiliary
output connection is necessary.
4.2.3 Two Wire Control: Relay / PLC Connection
An alternate connection for automated or unattended operation replaces
PTC
OPTO
the start/stop push buttons by connecting a dry (voltage free) maintained
contact closure between terminals 1 and 3 as shown in Figure 4.2.3.
When this contact is closed, the TE Series starter will start and run.
When it is opened, it is the same as a Stop command.

4.2.3.a
When using the Auto Reset functions (F052 – F053), special
consideration must be given to using 2 wire control. Refer to section
5.6.8 for details on using Auto-Reset functions.

Note:
When a maintained contact is used for start/stop it is advisable to set
the overload relay to the manual reset position. This will prevent the
motor from restarting if the thermal overload trips and then cools
down.
CAUTION!
Control Terminals 1-10 of TB1 are configured using solid state
devices powered internally with a 24VDC power supply. To prevent
damage to the TE Series control board, use dry (unpowered)
contact closures only when connecting to these terminals.
If existing 120VAC or other powered control circuit must be
interfaced, use interposing relays.
4.2.4 Interlock Connection
TB1 provides a connection point for an external dry (voltage free) N.C.
PTC
OPTO
(Normally Closed) interlock device between terminals 4 and 5. Examples
where this interlock connection would be used include low oil, high
temperature, or excess vibration dropout from user supplied devices. A
factory-installed jumper is provided which allows the TE Series unit to
operate if external interlocks are not used. If this jumper is removed and
an interlock is not used, the TE Series unit will not function.
