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.

sensitive edge) which must be compliant 
with regulation in force.
