6.3 - Connecting a buffer battery
The control unit is prepared for the installation of the buffer bat-
tery mod. PS224 (optional accessory): 7.2 Ah with built-in battery
charger.
To connect the buffer battery, proceed as shown on the side.
CAUTION! - The electrical connection of the buffer battery
to the control unit must be done only after completing all the
installation and programming phases, since the battery is an
emergency supply.
6.4 - Connecting the status light and diagnostics
The control unit is ready for the connection of a 24 V - 5 W max
warning light to the "light" terminal of the button panel board inside
the box lid (picture on the side: terminal 1 - 2+).
The "light" can be installed on the same box lid making a hole or out
of the control unit at a maximum distance of 2 m from it.
WARNING - The output is not protected against shortcir-
cuits.
This "light" works as follows:
- OFF = when the safety chain is open (ing ALT, STOP button, red
or release)
- flashing (0.5 s ON, 0.5 s OFF) = when it works correctly
- behaviour as the diagnostics of the OK led, red = when some
components require diagnostics.
6.5 - Open and Close block (using the buttons on the
box lid)
In the button panel board inside the box lid, there is a two-way dip
switch that allows activating the Open and Close buttons.
- OFF position = the buttons are disabled.
- ON posi tion = the buttons are enabled.
WARN ING - The STOP button is always active.
WARNING - To perform the learning procedures, the dip
switches must be activated to be able to use the buttons.

DIAGNOSTICS
7.1 - Messages on turning on
When the control unit is switched on, the behaviour of the OK led is significant as shown in Table 5, in particular:
- if learning the opening and closing positions is correct
- if learning the safety device ( sensitive edge) is correct and what type of device has been recognized..
Signal when the control unit is switched on
Clear memory (no position or safety acquired)
Positions acquired and STOP 8.2KΩ
Positions acquired and STOP OSE
Motor with electromechanical limit switch
Motor with incremental encoder
Motor with absolute encoder
After the messages shown in Table 5, the control unit shows any errors: see paragraph 7.2.
