CT06 8
- No PSTN telephone line
This condition is determined by the negative outcome of the PSTN line test (see
paragraph 8.10). The output is reset if the telephone line is detected during the
following test.
- Absence of PSTN card
The communicator checks the presence of PSTN card. Card extraction will cause the
output to switch and PSTN fault to be displayed. Output return to rest status (recovery)
is by fitting the card again into to the communicator.
Telephone FAILURES are also signalled by the LED on the front panel which blinks fast.
The LED will blink slowly after the condition which caused the failure is restored to
indicate that the event has been stored in the memory.
The memory signal can be cancelled manually by means of “Clear Data” in the Wieving
System Status menu (see pag.20)
The probability of positive call cycle outcome is proportional to the number of pro-
grammed telephone numbers. For this reason, YOU ARE ADVISED TO PROGRAM MORE
THAN ONE TELEPHONE NUMBER.
U3, U4, U5 OUTPUTS
• U3 and U4 outputs are electrical while output U5 consists of a free exchange C-N.C.-
N.O. relay. U3 and U4 present 0V when de-energised (+12V active). The relay dedi-
cated to U5 is de-energised. The outputs can be programmed as: Not Used, Associated
to inputs I1 and I2 or Controllable (remotely or locally by menu).
1. An output programmed as Not Used will be always de-energised.
2. An output programmed as Linked to an input (I1 or I2) will be activated according
to the associated input conditions. It can be programed as maintained or timed (5
sec/10 sec/30 sec/60 sec/90 sec).
• Associating an output to an input makes the output activate (switch) and return to de-
energised condition in different ways according to the type of associated input.
- If the associated input is 24h , the output will activated (switched to +12V) when the
associated input status changes from de-energised condition.
- Two cases are possible if the associated input is programmed as AND TC :
. With TC OFF, input status change will activate the associated output. Furthermore,
if the input is programmed as delayed, the associated output will be activated at
the end of the delay.
. With TC ON, input status change will be ignored. Consequently, the output will not
be activated.
- Resetting of an output can occur in different ways according to the programming:
· If the output is steady and associated to a 24h input, it will stay up until the user code
(or engineer code, where enabled) is entered by means of the keypad.
· If the output is steady and associated to an input in AND with TC , transition of
the TC to ON will instantaneously reset the output. Alternatively, this can be obtained
by entering the user code (or engineer code, where enabled) on the keypad.
· If the output is timed , it will reset to stand-by at the time-out also according to the
methods described for steady outputs (keypad codes and TC inputs) if waiting for
time-out is not required.
. The output will not switch if the associated input is programmed as Not Used .
3. If an output is programmed as Switchable , maintained or timed, refer to Chapter
5.4 “ANSWERING SERVICE AND REMOTE CONTROL OPERATION” for details. NOTE:
Only the status of
“Switchable outputs” can be varied by means of the “Switch
Output ” menu.
