1) INPUT DESCRIPTION
The lock has three digital input (active low) to open it controllable by shorting the pins to GND with a dry contact.
If an open collector device is used, make sure the polarity is correct (i.e. collector/drain connected to IN –
emitter/source connected to GND)
IN1 = open the lock
IN2 = close the lock
IN3 = open followed by an automatic closure
The input signal must be a pulse.
1.a) HOW TO OPEN THE LOCK
Send a pulse (duration from 500 to 1500 ms) to the IN input you will get the full opening of the lock (latches and latch
bolt). The closing will take place automatically when you close the door.
2) OUTPUT DESCRIPTION
Five digital outputs of the type "open collector" provide the following information:
OUT1 : state latch bolt => (OPEN = outside ; CLOSE = inside)
OUT2 : state latches => (OPEN = not outside ; CLOSE = outside)
OUT3 : state door => (OPEN = open ; CLOSE = close )
OUT4 : error => (OPEN = all is OK ; CLOSE = error )
OUT5 : battery status => (OPEN = charged ; CLOSE = low)
Each output is TTL compatible (5V dc) and must comply with the following electrical requirements:
ABSOLUTE MAXIMUM RATINGS
Io sink max. <= 20 mAdc
Vo open max. <= 6 Vdc
Vo saturation max. <= 0,8 Vdc
These outputs are available only when the lock is awake, otherwise they are all "open" (N.O.) to reduce
consumption of energy.
To wake up the lock without opening it, piloting the input IN with a short pulse duration from 50 to 100 msec., the
status will be available immediately after the pulse, and the lock will remain awake for an additional 3 sec. (TIMEOUT
period).
N.B.: The times indicated in charts are only for examples.

3) HOW TO GET THE STATUS OF THE LOCK AND OPEN IT
Before performing a maneuver we suggest to know the state of the lock, then make an opening. The lock remains
awake (providing its status) for all the time necessary to complete the maneuvers.
In the following example we show this general sequence:
a) Wake up the lock with short time pulse at input IN (see the time 0.5 sec. in the charts).
b) read the status of the lock.
c) if necessary, open the lock with pulse at input IN (see the time 1 sec. in the charts)
d) wait for the lock to perform the work ( max 15 sec.).
e) finished the movement of the latches, lock still showing their status for 3 sec. (TIMEOUT period) then goes into
sleep.

All these signals are in D.C. and referred to ground .
4) ERROR SIGNAL
When this signal is active there may be one of the following errors:
- stall of the latches
- Latch bolt not completely escaped
- Request the opening operation with the lock and door already open
- Accidental opening of the door during the closing operation,
- Detected the missing of mechanical cylinder (if equipped with a special sensor).
- latches or latch bolt in the wrong position
When the lock goes into sleep, error signal is reset.

5) INCREASE THE OPENING TIME OF THE LATCH BOLT
When you run a command OPEN (IN) the latch bolt comes out just after the opening of the door (dashed line).
If for some reason the door does not open, the latch bolt back outside after 10 sec anyway (Continuous line).

In case you want to keep the latch bolt inside for a longer time (max 2 minutes) while the door is still closed, you have
to keep active command OPEN (IN) for a long time: when the door is open, the latch bolt will be released immediately
outside.
If the door does not open the latch bolt will be outside 10 sec. after removing the OPEN (IN) command.
The following example keeps the lock open for a maximum time of 40 sec. If the door remains closed the OPEN (IN)
command (IN) will take up to 30 sec. after which the lock still holds the latch bolt for a further 10 sec. after that
releases it.
If the door is open during the 30 sec., command OPEN (IN) must be immediately removed.
In the graphs are indicated two cases: one in which the door is opened at the time 16 seconds (dotted lines) and the
other in which it does not open (continuous lines).
(NOTE : Check the port status through the signal OUT3 – state door)

6) POWER SUPPLY LOCK
Supply to the lock a mains voltage between 6.7 to 9.6 volts in direct current (Imax 2,5 A), or use 6 alkaline battery 1,5
V(Zn/MnO2) type "D" (LR20).
For mains voltage < 7.2 Vdc lock indicates that the battery is low.
For mains voltage < 6.6 Vdc the lock does not work.
