TECHNICAL ASSISTANCE AND REPAIR SERVICE 
Technical Assistance 
_.__ ----- - .-.. --- 
Should you experence difficulty with installation, checkout, or 
programming, and have made an attempt to isolate the problem using 
information provided herein; or should you encounter problems at a 
later date which cannot be resolved by refering to this manual, call 
the Comdial Technical Service staff. They can be reached at 
800-431-4345 (in Virginia: 800-654-3345) between the hours of 8:00 AM 
and 8:00 PM Eastern time, Monday through Friday. 
When calling for technical assistance, you should be at the job site 
and you should have in your possession, as a minimum, an accurate 
volt-ohm meter and a copy of this manual. 
Repair Service 
If your KSU or an individual station needs repair, subsequent to the 
warranty period, it may be returned to Comdial. Comdial will, at 
their option, either repair the defective equipment or replace it with 
a remanufactured unit. This repair will be done for a.fixed charge. 
For information on this charge, please call or write to the address 
given below. 
Comdial Corporation 
1180 Seminole Trail 
P.O. Box 7266 
Charlottesville, VA 22906-7266 
Attention: Repair Department 
Telephone: (804) 978-2400 
When returning equipment for repair, pack it carefully to prevent 
damage. Any damages during shipment will be the responsibility of the 
purchaser. The equipment should be shipped freight or postage 
prepaid. 
SECTION 2 
TROUBLESHOOTING 
FUSE LOCATION 
The KSU is protected against short circuit damage by a fuse located in 
the primary of the AC transformer winding. Fuse FS-1 is a 1 amp, 
25OV, SLO-BLO type fuse. The fuse holder is located near the top of 
the right side of the KSU cabinet. Always replace this fuse with one 
of the same value and type, otherwise, equipment damage could result. 
71  
						

							Maintenance IMI 66-037 
FAILURE ISOLATION 
The red LED located near the fuse holder is the system status 
indicator. This indicator should turn on steady when AC power is 
applied to the KSIJ. If the indicator flashes after power up, it 
could be indicating a processor failure. Unplug and reconnect W 
the AC power to the KSU and 
observe the LED indication. 
S.tatiqn Self Test 
--wi- m-w w e m - 4.6 iT 
Exercise the station self test feature as follows: 
1. Disconnect the line cord at the station base. 
IMPORTAMT NOTE 
THE ADJACENT ODD OR EVEM STATIOM WILL BE DISABLED 
DURING THE TIME THAT THE STATION LINE CORD IS BEIMG 
DISCONNECTED OR RECONNECTED. 
2. Press and hold the MUTE 
button, and reconnect the line cord 
to the station connector. The station will automatically 
perform a self test routine. Release the MUTE 
button as 
soon as the test begins. The sequence of the test is as 
follows: 
a. 
The line select indicators will light in sequence from 1 
to 8. 
b. 
The intercom select indicator will light. 
C. The speaker indicator will light. 
d. 
All indicators will turn off in the same sequence. 
e. The ringer will sound - Be sure that the ringer volume 
control is set to the medium or high volume setting. 
3. Replace any station that does not pass the self test. 
Test the DSS/BLF Console for proper lamp operation per the 
following procedure. 
1. 
Disconnect the console line cord plug from the line. 
2. Press and hold the station 10 select button while 
reconnecting the line cord 
plug to the line. 
IMPORTANT NOTE 
THE COMPANIOM STATION WILL BE DISABLED DURING THE TIME 
THAT THE CONSOLE IS BEING DISCONNECTED AND RECONNECTED. 
72  
						

							Maintenance IMI 66-037 
3. Release the station 10 select button, and note that the BLF 
indicators will each turn on in sequence beginning with the 
station 10 indicator. The indicators will then turn off and 
the console will become operational.

Pata Line Pairing 
All stations are even/odd paired on the data lines as shown in 
Table 3. Station 10 is paired with station 11, etc. If erratic 
light indications or ring signals occur at a paired station, an 
open data pair at either station may be the fault. A station 
with an open data line may work properly on a short loop but fail 
on a long loop. Test the station wiring per the checkout 
procedure given in Chapter 2. 
Overload Pairing 
All stations are paired as shown in Table 3 for overload current 
protection. If a fault occurs which causes more than 300 ma. of 
current to be drawn, 
the paired stations are disabled by circuit 
action. Disconnect the disabled stations and reconnect them one 
at a time to isolate the faulty one.

Figure 8 details a failure analysis flow chart to assist a 
service technician in isolating a failure in a defective system. 
One way to isolate a failure is to substitute a known good 
assembly for a suspected one. This is the recommended failure 
isolation method to use with the system. 
Connecting and disconnecting stations to the system does not 
affect the stored station auto/speed dial memory data. 
This data 
is stored in the KSU memory and not at the individual stations. 
Replacing the KSU, however, causes all stored memory to be lost. 
This includes all memory dialing numbers as well as all COS 
programming data.
