Photocells; Electric Block - Nice Spin10KCE Instructions And Warnings For The Fitter

7.3.2) Photocells

The SPIN control unit is equipped with the function "Phototest" which increases the reliability of the safety devices, enabling classification in
category 2 in compliance with the standard EN 954-1 regarding the combination of the control unit and safety photocells.
Each time a manoeuvre is started up, all safety devices are checked and only in the case of positive results can the manoeuvre be started.
If however the test fails (photocell "blinded " by sun, cables shorted etc) the fault is identified and the manoeuvre is disabled.
For the "phototest" function, a specific connection is required of the photocell transmitters (see fig. 40 and 41).
The control unit recognises the connection in "phototest" mode during the self-learning phase (see paragraph "4.2 Learning the door open-
ing and closing positions")
• Connection without "Phototest" function (Figure 38 and 39)
Power the transmitters and receivers directly from the control unit services output (terminals 3 - 6).

• Connection without "Phototest" function (Figure 40 and Figure 41):
Power of the receivers comes directly from the services output (terminals 3 - 6), while that of the transmitters is from the "Phototest" out-
put (terminals 8 – 6). The maximum admissible current on the "Phototest" output is 100mA.

If two pairs of photocells are used, which may interfere with the other, activate the synchronisation mechanism as described in the photocell
instructions.

7.3.3) Electric block

The factory setting of the "phototest" output is with the "Phototest"
function enabled.
Alternatively the output can be programmed on the SPIN control unit
for control of an electric block. On start-up of each opening manoeu-
vre, the output is activated for 2 seconds; in this way an electric
block device can be connected. The output is not activated during
the closing manoeuvre and therefore the electric block must have a
provision for mechanical reactivation.
The output can control the electric block directly, but only with loads
of 24Vac – 2W. The output must be interfaced with a relay, as shown
in the figure.
