3.8 OBSTACLE IMPACT CONTROL AND MOTOR FORCE ADJUSTMENT
With the SW2 microswitch 1 in the OFF status, obstacle impact is detected (during both the opening and closure
manoeuvres) by the encoder system which stops the gate moving and then reverses it by approx. 10 cm.
This control is switched off with the SW2 microswitch 1 in the ON status; in this case, other safety systems
compliant with regulations in force (e.g. sensitive edges) must be adopted. This is extremely important as
THE
INSTALLER IS LIABLE FOR THE SYSTEM AND FOR ENSURING ITS OPERATION COMPLIES WITH LEGAL
PROVISIONS
The
impact force is adjusted using the VELOCITA REGIME potentiometer during the normal working phase and using
the VELOCITA RALLENTAMENTO potentiometer during the slow-down phase; the adjustments must be performed
in compliance with the regulations in force.

3.9 CR/42 CONTROL UNIT TECHNICAL SPECIFICATIONS
CAUTION
The considerable differences in
temperature between summer and winter
can cause differing rates of expansion in
all materials, including those used for
manufacturing our motors. That is why we
recommend you check the impact force
setting at the start of winter and summer.

3.6 BATTERIES BACKUP (OPTIONAL)
It is possible to connect inside the MERCURIO 524 A two backup batteries
(2Vdc 1,2 Ah SERAI BT/14), in order to enable the automation to work for
a short period also in case of power failure. The batteries have to be
connected in series (see Picture aside); the positive cable has to be
connected to the clamp 2 (B) and the negative cable to the
clamp 1 (BATTERY )
3.7 MOTOR WORKING WITHOUT ENCODER
The control panel CR/42/24 has been conceived to work also without ENCODER, therefore can be used also
with other kind of motors 24Vdc. The control panel can be enabled to work without encoder acting on the micro
switches SW1 and SW2; in this case it is not necessary any programming, being the working phase between the
limit switches.

CAUTION: working without ENCODER,
the force limitation is disabled, other
safety devices must be adopted (e.g.
sensitive edge) which must be compliant
with regulation in force.
