Basic Installation and Operation Guide
Output (Auxiliary) Relay Contacts
Three programmable auxiliary relays are on TB2. The TE Series starter comes with three programmable dry
relay output contacts. Outputs 1 and 2 are Form C (SPDT), with a Common, N.O. and N.C. Output 3 is a
Form A, (SPST), N.O. contact. It is not necessary to use the programmable output auxiliary relays in the Start
/ Stop circuit. An internal seal-in relay is provided elsewhere (see 4.2.2.a). Toshiba recommends fusing all
outputs with external fuses. The relays are rated for 240 VAC, 5 A and 1200 VA.
Installation, Operation and Programming Manual for additional relay programming details.
Note:
It is not necessary to use the programmable output auxiliary relays in the Start / Stop
circuit. An internal seal-in relay is provided elsewhere (see "Three Wire Control
Connections").
Bypass Contactor Control
On TE...-BP starters, an internal dedicated connection is used at the factory for automatically controlling the
Bypass Contactor. Field wiring for Bypass Contactor operation is not required.
Independent Bypass Contactor Control
The TE...-BP Series starters use standard industrial contactors that can be controlled independent of the
starter electronics if necessary. When doing so, it is necessary to size the starter based upon the ATL
(Across-the-Line) selection chart so that the contactors are rated for ATL duty instead of normal Shunt Duty.
(See Section 1.2.3.of the Advanced Installation, Operation and Programming Manual). Supplemental
overload protection will be required (See Section 3.1.3.of the Advanced Installation, Operation and
Programming).
Units have external terminal blocks marked for this purpose (see Appendix 5 of the Advanced Installation,
Operation and Programming Manual for additional for drawings). Dry (voltage free) contact closure between
these terminals will close the bypass contactor immediately. The Bypass Contactor coil voltage is the same
as the control voltage (120VAC unless the optional 240VAC control is specified), and the voltage on these
terminals is the same as the coil voltage.

TE Series Digital Solid State Soft Starters 18 – 1250A
Factory default settings for these relays are as follows:
AUX 1 – Run / Stop (see F060).This contact changes
state upon a Start command, returns to normal on Stop
(or Begin Decel if active).
AUX 2 – At-Speed / Stop (see F061).This contact
changes state upon the TE Series detecting At-Speed,
and returns to normal on Stop. At-Speed is determined by
the TE Series detecting the current dropping after
reaching End-of-Ramp.
AUX 3 – Any Trip (see F062) this contact closes when
any trip condition 5 – 15 (as defined in Table 5.6.10 of the
Advanced Installation, Operation and Programming)
occurs.
All relays can be reprogrammed for a wide variety of
functions. See Section 5.6.9 of the Advanced
