4.2.7 Fault Signal
An optically isolated Triac output is dedicated as a fault indicator on TB1,
terminals 11 and 12, labeled “
Opto
”. The output Triac switch is rated for
10 - 250 VAC,
50 mA (maximum)
. If the three programmable Output
Auxiliary Relays are being used for other functions, this output can easily
be hooked up to a PLC or small external relay to provide a Fault signal.
This Fault Output operation is permanently fixed at “Any Trip”,
duplicating the Relay setting 16 as shown in Table 5.6.9.
This output is permanently set to this function and is not
programmable.
4.2.8 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.
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, or a maximum of 30 seconds
after Start.
AUX 3
– Any Trip (see
F062
) This contact closes when any trip
condition 5 – 15 (as defined in Table 5.6.9) occurs.
All relays can be reprogrammed for a wide variety of functions. See
Section 5.6.9 for additional relay programming details.
