Correct voltage 24 – 32VDC measured
on terminal block X7 no.1-2 in the CU-
unit
Indication from failure contact X2
No.5-6(NO)or. X2 No.6-7 (NC)

Two possibilities
1. 230V AC or 115V AC failed and
have been switched to 24V DC
Emergency.
2.The power supply module has failed.
No audio message received in any
substation no. 1-10 or 11-20.
One or more operation panels failed.
One or more Indication light is active ,
one for each operation panel marked
"indication for panels" on central
unit.ref.dwg.CU-100_lo
System CTB-100V
Tested, ok
Recommended Action
1.Check 24V DC mains power
supply or power supply SPS-4
2. Check fuse marked F3 1AT
(Ref. dwg CU-100_lo)
1. Check main power supply
2. Check fuse 5.0AT , terminal
marked 3
2.1 If not success, the power
module have to be repaired./

is set according to chapter 3.5
Check if DIP switches in the
central unit marked "set receive
call" is set according to chapter
3.6

chapter 3.7
Adjust trim potentiometer in the
central unit marked "adj. aux.
input signal" to satisfactorily
level.see chapter 3.8.2
Adjust trim potentiometer in the
central unit marked "adj. PA-
output signal" to satisfactorily
