7.2 Level for call signal out to all
lines does not fulfil the
requirement.
Adjust trim potentiometer in the
central unit marked “adj. call
signal out” to satisfactorily level.
See chapter 3.8.3
8 General operating problems
occurred when operating
several stations.
Instability. Check cable and termination
blocks in the CU unit for
respective stations. And especially
cable and termination blocks in
junction boxes, if used.
9 One substation can not be
operated No contact between CTB panel and
substation Check cable and terminal block in
the CU unit for current extension.
Check cable and terminal block in
the substation or plugbox. Move
this terminal block to a another
ext. number.
If operating is ok, current
substation have to be repaired.
10
Operation problem from an
substation. Continuous rapping tone (pip..pip) in
the CTB units. Change polarity in substation
terminal no1-2
11 No signal in substation when
using the sign push button on
the CTB- unit. No audio 1Khz tone in the substation Disconnect the substation.
1. If 7V AC is measured on
terminal X8 1-2 in the CU unit,
this unit is ok.
2. If no voltage measured, the CU
unit have to be repaired
3. Connect the substation.
If no voltage measured on
terminal X8 1-2 in substation,
fault must be in cable or the
substation have top be repaired.
12
No signal in additional signal
device when using the sign
push button. Signal in substation, but no signal in the
additional signal device. Disconnect the substation.
1. If no voltage measured on
terminal X8 3-4 in the CU unit,
check fuse F3 1A.
2. If fuse F3 is ok.
Check automatic fuse by waiting
2-3 sec. If 24V DC is measured,
the load is to high Max. 50mA.
13
Feedback problems In one CTB unit Move substation or parallel
equipment to another position.
14
Problems with system
generated noise
1
Occurred both in central unit and
substations if it used ships own 24V DC Disconnect ships 24V DC and
connect a separate power supply
(SPS-4) or a DC 24V / 24V DC
converter.
14.1 Problems with system
generated noise 2
Occurred both in CTB units and
substation, (substations) 1. Check all cable connections,
especially the screens. Important
that connections is done according
to requirements in chapter3.4 and
dwg.CTB-100_cc1, CTB-100_cc2
CTB-100 _cc3, CTB-100 _cc4,
CTB-100_cc5, CTB_cc2,
CTB_cc3 and CTB_cc6
2. If still problems, try with an
capacitor 1uF between terminal
no.1-2 block X8-10 (20)
If still problems, it will require
service from Zenitel.
