DISPLAY
DESCRIPTION
Deceleration point percentage:
this parameter is used to set the length of the decelerated section, selecting from the
two set values.
H0
40% of maximum memory-stored opening
H1
20% of maximum memory-stored opening
Speed during deceleration phase:
this parameter is used to set motor speed during the deceleration phase, selecting
it from the two values.
i0
High
i1
Low
Limit-switch operation:
this parameter enables you to select operation with or without the limit-switch.
L0
Operation without limit-switch
L1
Operation with limit-switch
Number of motors:
this parameter is used to select the type of gate: with one leaf or with two leaves
N1
Single-leaf gate, only one motor connected
N2
Double-leaf gate, two motors connected
10. PROGRAMMING
Before you begin programming, select the type of operation for the control unit: with or without encoder (see
paragraph 6).
During the programming procedure, the control unit memory-stores the opening, closing mechanical stop points and
any pause time before re-closure.
1- Release the gearmotors, locate the leaves at half open point, and re-lock the operators.
2- Power up the control unit and check if value “
--
” is shown on the display.
3- Press and hold down push-button
P2
until the display shows the first parameter and relevant value.
4- Give an
OPEN A
command with any device connected to this input: the display shows value “
Pr
”, and the leaves
begin to move. The first manoeuvre performed by the leaves must be closing. If this does not happen, stop the
gate movement with a reset pulse. To do this, make a bridge between the two “
RESET
”
PINS
, using the connector
(see Fig.04). Cut power and put the connector back in its normal position (Fig. 04). Then change over the wires of
the motor/s, which had performed the opening operation. Resume the programming stage from point 1.
5- When the closing mechanical stop point is reached, the gearmotors pause for about 2 seconds, and then restart
with a total opening manoeuvre up to the opening mechanical stop point or up to the relevant limit-switch.
6- If automatic reclosure was not enabled, this means programming has finished, otherwise the control unit begins
counting pause time.
7- When the required time has elapsed, give another
OPEN A
pulse, and the gate will begin to close.
8- When the closing stop has been reached, programming
has terminated, and the display shows value “
--
”.
• The display shows value “” during the entire pro-
gramming procedure.
• The flashing lamp stays lighted on a fixed light
during the entire programming time.
• Leaf movement is decelerated during the pro-
gramming procedure.
11. OPERATION OF ELECTRONIC CLUTCH
This is a very important device for reasons of safety. Its setting stays unchanged long-term, without wear. It is active
during both closing and opening. When it operates, it reverses gate movement without disabling automatic closing
if activated.
If the clutch operates several consecutive times during the closing movement, the control unit goes into
STOP
status,
disabling any automatic command. If the clutch operates several consecutive times, this means that the obstacle
remains and it could be dangerous to perform any manoeuvre. To restore normal operation, the user must give an
OPEN A / OPEN B
pulse.
