The PM8000 control box is designed to operate one-or two-wing swing gates.
It is intended to operate 2 single-phase 230V ac electric motors of 1 HP maxi-
mum power.
Technical description
PAUSE TIMER Adjustable between 2-100 seconds. It is located on the main board and,
after the present pause time and after every opening, it closes the gate automatically. A
start impulse given during the pause phase, either from the photostop or photocell, re-
starts the timer from zero - fig.5.
WORK TIMER Adjustable between 0-100 seconds. Located on the main board, after the
operation time selected, it blocks the opening or closing operation. (Set 2-3 seconds mo-
re than the time needed for one operation) - fig.5.
DISPLACEMENT TIMER FOR CLOSING Adjustable between 0-25 seconds. During clo-
sing it delays the start of motor M2 until after motor M1; with 2-wing doors it is essential
to set the delay of M2 for closing in compliance with safety regulations; the second wing
(with electric lock) must start closing only after the first wing has moved at least 30°. With
single-wing doors, connect the motor to terminal M2 and zero the displacement timer -
fig.5.
DISPLACEMENT TIMER FOR OPENING When opening, motor M2 starts 3 seconds
before motor M1 unless the displacement timer for closing has been zeroed.
TIMER REGULATION The timers for pause, work and displacement when closing, mu-
st be set only at the end of the cycle. Settings made during the cycle are not memorized.
COUNTER - MEM The counter acts as a real limit switch, e.g.: a start command given
5 seconds after the start of the closing operation, cause re-opening for exactly 5 se-
conds. The counter memorizes, instant by instant, the time elapsed from opening or clo-
sing: the rapid inversion of movement causes the preset time to replace the memorized
time on the work timer. This permits the preset pause period to be kept constant and sa-
ves the motors, which are without limit switch, from sliding their clutch more than neces-
sary, thus reducing overheating.
TORQUE REGULATION The trimmer fitted on the torque regulation board allows the
motor thrust to be regulated just enough to cause movement, so as to limit the damage
caused by an eventual collision between the moving gate and persons or things. After
completing installation, adjust the power output from the control box using the trimmer,
checking that the motor, once started, can be stopped by opposing light resistance to ga-
te movement (reduce by turning trimmer anticlockwise) - fig.8.
MAXIMUM TORQUE The motor starts with maximum torque and after 1,5 seconds con-
tinues with the preset minimum torque; this allows the greater resistance to be overco-
me with the initial torque of the motor.
SINGLE WING When the control box is used with a single wing gate the reduction mo-
tor must be connected to M2 and the displacement trimmer RV2 must be zeroed.
EXCLUSION OF TORQUE REGULATION CARD This card can be excluded by remo-
ving it from its socket. The connections to terminal (8) must however be made good with
a jumper across the two pins, at the top of the socket (use a female "faston" terminal: 6,3
UNI 4894 - 250 Amp) - fig.6.
FLASHING LIGHT The flashing light logic device is incorporated in the control box. Use
flashing light without logic and connect them to the terminals (9-10).
STATE OF FLASHING LIGHT
During opening, flashing is
During pause phase, light is
During closure, flashing is
When finally closed, light is
SPY LIGHT A spy light of 220V in parallel with the flashing light copies its operation,
showing at a distance the various phases of the cycle.
DOUBLE ENTRY PHOTOCELL 1
st
(15-16) operates during closure and pause; its interruption during closure causes mo-
mentary arrest of movement and then a rapid inversion of movement; during the pause,
with the timer in action, it interrupts and zeroes the timer counter, which starts afresh
when the photocell is free. When led LD4 is on, this indicates correct connection and ali-
gnment of the photocell. 2
entry photostop: the photocell connected to terminals (15-
nd
18) is always operative, its interruption in opening or closing arrests gate movement,
which restarts, in the opening mode, only when the photocell is free; during the pause,
with the timer in action, it interrupts and zeroes the timer counter, which starts afresh
when the photocell is free.
When Led LD6 is on, this indicates correct connection and alignment of the photocell.
Usually on wing gates the internal photocell is connected to the "Photostop" to ensure
protection for users who are leaving, even during the opening phase.
STOP COMMAND A "stop" impulse on terminals (15-17) arrests all functions. A "start"
impulse restarts the cycle, causing reopening for the time memorized during the move-
ment phase prior to the stop. When led LD5 is on, this indicates correct connection and
functioning of the "stop" command.
DELAYED INVERSION Inversion of movement is always delayed by about 1,5 seconds.
DOUBLE ENTRY OF START - 1
entry start: a start impulse on terminals (15-20) starts
st
the programmed work cycle by activating both motors as planned. During the pedestrian
start cycle, the start command is inactive during opening and pause, while it is active du-
ring closure. 2
pedestrian start entry: a start impulse on terminals (15-19) starts the
nd
programmed work cycle by activating only motor M2. Normally used for entry of pede-
strians. The pedestrian start command is inactive during the start cycle and it becomes
active at the end of the cycle.
ELECTRIC LOCK At the beginning of every cycle on terminals (11-12), an impulse acti-

COURTESY LIGHT OR ELECTRIC BOLT (Fig. 12) In the control box there are two ter-
minals (25-26) to which either a courtesy light (max 350 w) or an electric bolt (230V) can
be connected. Contact SW2 allows in the open position the connection of a courtesy li-
ght and in the closed position the connection of an electric bolt.

OPERATION OF ELECTRIC BOLT This will operate only during operation of the motors.
It is possible to connect up with the electric bolt a courtesy light of 100 watt max which
will light up at all times the motors are operating.
CLOCK (Fig.11) A daily or weekly timer clock can be connected if it is desired to leave
the gate open at certain hours of the day. This can be done only with Programme 3 (au-
tomatic condominium). 230V clock. The two contact wires of the clock have to be con-
nected with 19/20 Start.
RAMMING (INITIAL BOOST) Each cycle is preceded by a brief thrust in the closing di-
rection, imparted by the motors, to facilitate release of the electric lock. This is activated
by putting Dip 3 to ON (Fig.9).
SOCKET FOR RECEIVER The control box has a socket (Fig.7) for a single-channel or
double-channel radio card.
LED When the green led LD1, located on the main board, is alight confirms the electric
power supply of 230V ac.
PROTECTION A 5A fuse protects the 230v circuit while a 2A fuse protects the low ten-
sion. The external inputs (movement limiter, photocell, etc.) are optically protected.
CAUTION Interrupting the photocells or leaving the start button pressed longer than ne-
cessary, during the pause phase, risks fusing the flashing lamp. To leave the gate open,
open it with "start" and block it with "stop". In case of malfunction, check whether the
power is on (led LD1 alight), check the fuses, check the connections in the terminal box
remembering that the contacts for stop, photostop and photo must normally be closed
while the contacts for start and pedestrian start must be normally opened.

CAUTION Installation must be done in compliance with current regulations by professio-
nally qualified personnel. Motorized gates, doors and main doors must be built and pro-
tected in compliance with accident safety regulations. For electrical safety, check that all
metal structures are correctly connected to an efficient earthing system.
The size of cables and protective systems must be adequate for the maximum power of
the equipment installed.
ATTENTION Since the direction of the opening movement changes depending on the lo-
cation of the motor, on the right or left of the entrance, after all connections have been
made check that at the first start command the motors open the gate. If not, invert the wi-
res on the terminals (3-4 for motor M1; 6-7 for motor M2).
Check also that motor M2 moves the wing with the electric lock, i.e. the one which clo-
ses last. If it is desired to use the control box, the photocell, the stop button and the pho-
tostop being disconnected, fit jumpers across the respective pairs of terminals (in order,
15-16, 15-17, 15-18). Absence of just one of the jumpers envisaged (NC) blocks opera-
tion of the control box.
To visualize the state of the control box during operation, the flasher or spy light (230V)
connected to the terminals (9-10) indicates the following: Programme1 (Step by Step)
and Programme 3 (Automatic Condominium) during opening rapid intermittent light;
during pause light off; during closure slow intermittent light; when closed light finally
off - Programme 2 (Automatic Step by Step) in contrast to Programmes 1/3, light stays
on during the pause phase.
To visualize the correct connection and operation of the photocells (LD6), the stop com-
mand (LD5) and the photostop (LD4) check that the respective Leds are on.
