3) Using relay codes
After programming is completed, you can activate relay 1 by simply entering:
55127 E. In this example, the operating mode has been set to 0, in other words,
bistable (on/off).
To activate monostable operation, refer to point 5.
• Up to 300 codes can be set relay 1 or relay 2. If you attempt to enter a code
which has already been stored, an error is indicated.
4) Cancelling relay codes
The following procedure cancels stored codes from memory:
1) Enter
“0”
and
“E”
(start programming procedure code)
2) Check that the LED has lit up.
3) Enter the
supercode
(see point 1), then
“E”.
4) Enter
“0”
(cancel code) followed by
“E”.
5) Enter the code to be cancelled, followed by
“E”.
6) The LED should now turn off.
Example:
to cancel code 55127, enter in sequence:
0 E
start procedure
12345 E
supercode
0 E
cancel
55127 E
code to be cancelled
5) Bistable/Monostable operation
The relays can be programmed to operate in bistable (on/off) or monostable
(timed) modes (the period of activation can also be set in the latter case).
Bistable mode:
entering the value
“0”
sets the relay to activate when the code is first entered,
then de-activate when it is next entered.
Monostable mode:
entering a value in the range
1
to
99
sets the relay to activate when the code is
entered and de-activate automatically once the specified period of time (1 to 99
seconds) has expired.
Modifying relay timing
To modify the relay timing, first cancel the relay code as explained in point 4.
Example:
if relay 1 was activated with code 55127 in bistable mode, proceed as follows to
change its mode to monostable:
1) Cancel the code by entering in sequence:
0 E
start procedure
12345 E
supercode
0 E
cancel
55127
E
code to be cancelled
2) Re-enter the code with the desired operating mode:
0 E
start procedure
12345 E
supercode
1 E
identification
5 E
monostable mode, 5” delay
55127
new code.
After this, relay 1 will activate on entry of code 55127 in monostable mode for 5”.
6) Anti-coercion function
When the operator must be able to send an alarm without being noticed, the anti-
coercion function can be activated. The anti-coercion function, composed of a
single digit, must be entered after one of the relay codes, and activates not only
the relay in question, but also the timed anti-coercion output (5”) (AC for Art. 3188
or AL for Art. 3328).
Programming the anti-coercion function:
1) Enter
“0”
and
“E”
(start programming procedure code)
2) Check that the LED has lit up.
3) Enter the
supercode
(see point 1), then
“E”
.
4) Enter
“4”
(select anti -coercion function), then
“E”
.
5) Enter the
anti-coercion code
(1 digit from 1 to 9), then
“E”
.
6) The LED should now turn off.
Example
to set an anti-coercion code of 3, enter in sequence:
0 E
start procedure
12345 E
supercode
4 E
anti-coercion function
3 E
anti-coercion code
Now, when the relay code is followed by the anti- coer cion code, the output relay
as well as the anti-coercion output will both be activated (the latter timed to 5”
approx): 71032 3 E.
• The anti-coercion code MUST be entered after the relay code and before
the final E.
• When the anti-coercion function is activated, the relay code may not be
more than 7 digits long.
• The relay code may not terminate with the digit selected for the anti-
coercion function activation code.
• The anti-coercion output is of the open collector type (500 mA max).
7) Programming the allowed errors number
This allows you to set the number of code entry errors allowed before the locking
function is activated.
If, for example, you set a value of 3, on the third incorrect code entry the key is
locked for a period of 1 minute. You can also send an alarm signal (output
AL
),
after the allowed number of errors, if this is provided for during programming. To
send the alarm, program “1” during the procedure, otherwise program
“0”
(see
below).
An incorrect code entry is the entry of a code not stored during programming,
followed by
“E”
.
Programming the allowed errors number
1) Enter
“0” “E”
(start procedure).
2) Check that the LED has lit up.
3) Enter the supercode (see point 1), followed by
“E”
.
4) Enter the number
“5”
(error lock function) followed by
“E”
.
5) Enter the allowed number of errors (1-9), but DO NOT enter
“E”
.
6) Enter:
“1” “E”
to send an alarm when the key is locked;
“0” “E”
if you do not
wish to send an alarm.
7) The LED should now turn off.
Example:
to program key locking after 3 errors without sending an alarm, enter in sequence:
0 E
start procedure
12345 E
supercode
5 E
error function
3
number of allowed errors
0 E
do not send alarm
8) Programming the relay 1 activation delay for a remote key input
This procedure sets the activation time for relay 1 on a remote input. Values from
1 to 99 can be set. The default timing is 5 seconds.
Example
:
To set the activation time to 10 seconds, enter in sequence:
0 E
start procedure
12345 E
supercode
6 E
Remote Key timing function
10 E
relay activation time
ENABLING THE “KEY” BUTTON
A
Short-circuiting terminals CK1 and CK2, for example via a timer, makes it possible
to activate relay 1 without entering the relay code but by simply pressing the “key”
button
A
.
RESET INPUT (Art. 3188 only)
Connecting this input with the negative (GND) completely locks the keypad and
de-activates all outputs (relays and alarms).
REMOTE KEY INPUT (RK)
Closing this contact with ground activates relay 1 for the set time (see point 8). The
contact can be connected remotely up to 20 m max.
