Diagnostics & Trou ble shoot ing
Digital Outputs:
1. IMPORTANT! - The following steps can not be
per formed until the Motor Controller connection
be tween TB6-1 and TB6-53 has been re moved.
This connection could be a jumper or it could be
a connection from external devices in the starter.
The Pro gram will pre vent manual control of Digital
Output devices until this connection is removed.
2. The Digital Outputs are listed on this Screen ac-
cord ing to Relay and Triac number (KI, Q3, etc).
Fig ure 17 shows the external devices that are con-
nect ed to these Relays and Triacs and the func tions
of each one.
3. Press SELECT key. An arrow will appear ad ja cent
to Relay KO.
4. Select a relay or triac for manual control by using
the
▲
and
▼
keys to place the arrow ad ja cent to
the desired device.
5. Press the ENABLE OUTPUT key to enable the
se lect ed output. The LED adjacent to the selected
output should illuminate. If it does not, perform
KEYPAD Diagnostics test. If a relay is selected,
it should en er gize, closing its contacts. If a triac
is selected, it will turn on, energizing the device it
is connected to. If the relay does not energize or
triac does not turn on, per form appropriate trou ble -
shoot ing procedure below.
6. Press the DISABLE OUTPUT key to disable the
se lect ed output. The LED adjacent to the selected
out put should extinguish. If it does not, perform
KEYPAD diagnostic test. If a relay is selected, it
should de-energize, opening its contacts. If a triac
is selected, it will turn off, de-energizing the de vice
it is connected to. If relay does not de-energize or
triac does not turn off, perform ap pro pri ate trou-
ble shoot ing procedure below.
7. When all desired tests have been performed, press
DIAGNOSTICS key to return to the MAIN DI AG -
NOS TICS Screen.
8. Install Motor Controller connection from TB6-I to
TB6-53 removed in step 1.
Digital Inputs Troubleshooting:
If any of the Digital Inputs tests fail to perform as de-
scribed above, perform the following steps in se quence.
Refer to Figure 14 and applicable wiring di a gram ref-
er enced at the beginning of Section 23. If a defective
160
com po nent is found during any of the following steps,
re place the component as instructed and repeat the dig i tal
Inputs Pro ce dure above to determine if the problem has
been resolved.
1. Remove 1/0 Board ribbon cable. Using an Ohm-
me ter, perform a continuity check on I/O Board
rib bon cable J1-21 to J19-21, J1-22 to J19-22 and
applicable output pin of function that failed in Pro-
ce dure above. If an open circuit is de tect ed, re place
ribbon cable. Otherwise, install ribbon ca ble and
proceed to next step.
2. Measure the +5VDC supply voltage to the 1/0
Board on 1/0 Board between J1-21 and J1-22.
If >4.5VDC, proceed to next step. If < 4.5VDC,
dis connect rib bon cable at I/O Board J1 and re peat
the mea sure ment at J1. If <4.5VDC, replace the
Microboard. Re-install the ribbon cable.
3. With 115VAC (± 10%) applied to the I/O Board
dig i tal input that failed in Procedure above, the ap-
pli ca ble I/O Board output at J1 should be at a Log ic
low level (<1.0VDC). If it is >1.0VDC, re place the
I/O Board. If the output is at a Logic Low lev el, the
applicable LED should be illuminated. If the LED
is not illuminated, replace the Microboard.
4. With 0VAC applied to the I/O Board digital input
that failed in Procedure above, the applicable I/O
Board output at J1 should be at a Logic High level
(>4.OVDC). If it is <4.OVDC, replace the 1/0
Board. If the output is at a Logic High level, the
ap pli ca ble LED should be extinguished. If it is not
ex tin guished, replace the Microboard.
Digital Outputs Troubleshooting:
If any of the Digital outputs tests fail to perform as de-
scribed above, perform the following steps in se quence.
Refer to Figure 17 and applicable wiring di a gram ref-
er enced at the beginning of Section 23. If a defective
com po nent is found during any of the steps, replace the
com po nent as instructed and repeat the Procedure above
to de ter mine if the problem has been resolved.
1. Remove I/O Board ribbon cable. Using an Ohm-
me ter, perform a continuity test on the cable J1-25 to
J19-25, J1-26 to J19-26 and applicable output pin of
func tion that failed in Procedure above. If an open
circuit is detected, replace ribbon cable. Oth er wise,
install rib bon cable and proceed to next step.
2. Measure the +12VDC supply voltage to the I/O
Board on I/O Board between J1-26 (+12VDC) and
J1-25 (Gnd). If >11.0VDC, proceed to next step. If
