OPERATION WITH A TIMER
The control unit allows the connection of a
timer for programming door opening and
closing times.
To use this function, it is essential to set
function 3 (see FUNCTION TABLE) to
AUTOMATIC LOGIC
The timer should be connected between the
START (L1)
and
COMMON (L3)
terminals.
Each time the timer closes the contact, the
automation device opens the door and remains
paused until the contract is released. At this
point the countdown starts, for the length of
the pause time set, after which the automation
device closes the door.
CASE WITH KEYPAD
The EASY3 and EASY4 control units may be
installed in cases with external keypads
(accessory codes 171226).
To use the keypad buttons, it is essential to
install adapter 171226 as shown in the figure.
Alternatively, the WES-EASY accessory may be
installed (code 35B025), which besides using
the keypad allows controlling the edges by
radio using the special sensors (see the
WES-EASY instructions).
The keypad buttons operate in parallel with the
terminal controls. These all remain active,
including the STOP command, and must be
jumpered to ground if not used.
Versions supplied with keypads also allow the
automation device to operate in MAN PRESENT
mode should the safety devices malfunction.
By pressing and holding the button on the
keypad, the automation device is activated
after 5 seconds, overriding the safety devices;
the motor stops immediately as soon as the
button is released.
