function 6
Emergency command - N.C. contact: to activate the input
between terminals 11 and 15 (see function 5), an opening
pulse of a N.C. contact is required.
Emergency command - N.O. contact: to activate the input
between terminals 11 and 15 (see function 5), a closing pulse
of a N.O. contact is required.
function 7
CODIS - temporary connection: the CODIS can be used only
initially to activate certain functions. When the external
programming unit is removed, the function that has been
activated remains stored. In this case, Level II is inhibited, and
the settings (speed, pause times, etc.) must be performed by
means of the internal 959 B-E programming unit.
CODIS - permanent installation: the CODIS is installed
permanently; the four operating levels are all active.
function 8
15 kg static force / 9 kg static force: this function makes
it possible to change the sensitivity of the anti-crushing
device.
function 9
CODIS inhibited inactive / CODIS inhibited active: this function
makes it possible to activate the CODIS electronic inhibition. In
this condition, no programming can be performed at any level.
To release the CODIS temporarily, press the “+” and “-”
pushbuttons in the following sequence:
“+ + - - + +”.
This operation may be carried out for two purposes:
1)
to change the operating function or modify some settings
at Level II; in this case, after 2 minutes the CODIS inhibition
will come again;
2)
to remove the CODIS inhibition; in this case, it is necessary
to access Level III and to disable that function.
function 10
Standard opening pause time: the pause time begins with the
door open and the control devices (e.g., sensors) inactive.
Immediate closing: the door closes when the control devices
(e.g., sensors) are inactive. In this case, directional sensors must
be used.
function 15
Restore STANDARD settings / Retain programmed functions:
this function makes it possible to check whether any function
has been programmed differently from the standard settings.
If at least one function has been programmed differently from
the standard settings, LED 6 is lit (ON).
In this case all the standard settings can be restored by
pressing the “+” and “-” pushbuttons simultaneously.
After this operation, it is advisable to perform a RESET.
function 17
TEST programme inactive/active: this function makes it possible
to activate consecutive operating cycles. The control devices,
in any case, take priority over the operation of the system. The
programme can be cancelled by performing a RESET.
function 18
Level II RESET active / inactive: this function makes it possible to
preserve the settings of the opening, closing and opening
excursion speeds even in case of a voltage drop or RESET.
function 19
STANDARD internal command: the activation of the internal
control device controls a complete door cycle (standard
operation).
STEP-BY-STEP internal command: the activation of the internal
control device controls a sequence of door opening / stopping
/ closing / stopping / opening, and so on.

the fault has been eliminated.
9. MAINTENANCE
It is advisable to check the automation unit once a year, in
order to make sure that the dragging system and closing spring
are in perfect working order.

Check the toothed wheels and, if necessary, lubricate them
with grease for gears or bearings

Important:
never use spray lubricants.
8.4. LEVEL IV - SELF-DIAGNOSIS
The CODIS programming unit has a self-diagnostic level, which,
in case of a fault, interrupts the display of the operating
function every 2 seconds in order to display the malfunction
condition for 0.5 seconds. The type of fault can be identified by
observing the combination of LEDs 1-5 that are lit together with
the red ERROR LED (see Table 8).
