system will operate normally.This is an added security feature should the property be unattended for an
extended length of time.
Lightning Protection
The CP75 controller has on-board lightning protection. The protection circuitry is based on a design
developed in conjunction with the CSIR. It is however important to realise that the controller's protection
only functions correctly if an adequate lightning earth is fitted during installation. Lightning damage is not
covered under the normal guarantee of the equipment.
ALTERNATIVE POWER SUPPLY
Solar Panel (Optional)
With the battery driven system, the battery may be charged using a solar panel in place of the
conventional charging circuit. A 20 Watt panel will provide on average 10-12 daily operations of an
average gate without causing the battery to discharge over a period of time. (The allowable number of
operations will be reduced if 12V DC security lights are fitted). It is necessary to have at least a 35A/h deep
cycle, low maintenance battery fitted, in order to provide sufficient back-up capacity during days of poor
weather
All gate operators have a means of manually operating the gate in the event of a total malfunction of the
equipment.
If one is locked outside the property, the padlocks connected to the clevis pin through the gate bracket
can be unlocked. This will allow the clevis pin to be removed and the linkage arm to swing away from the
gate. This will allow the gate to be opened sufficiently to allow a person to enter.
Once inside the property, to release either operator complete the following procedure:
Swing the connecting arm to the side and open the
gate.
