LIMIT SWITCH
General description:
the electronic control box ELPRO 37 DB has been developed to provide a reliable unit to control single or double swinging gate, fitted with pressure valves; single-
three-phase 230/400 V - 50/60 Hz. The manufacturer is not liable for any incorrect use of this appliance; and also reservesthe right to change and update it without
previous notice.
IMPORTANTE PER L'INSTALLAZIONE E IL CORRETTO FUNZIONAMENTO:
- The control box must be installed in a dry and sheltered place.
- Make sure that power supply to the control board be 230/400 V ±10%.
- Make sure that power supply to the electric motor be 230/400 V ±10%.
- For distances longer than 50 metres increase the section of the wires.
- Fit the mains to the control box with a high sensitivity, 0,03 A, differential, magnetic-thermal circuit breaker.
- Cables with 1,5 mm² section wires are to be used for the power supply, electric motor and flasher for distances up to 50 m.
- Cables with 1 mm² section wires are to be used for the limit switches, photocells, push buttons and accessories.
- If no photocells are used link out terminals 1 and 2.
- If no stop button is used link out terminals 3 and 6.
- Open/close motor run time trimmer must be always superior to the time actually required for the gate travel.
N.W.: For applications such as light switching, CCTV, etc. use solid state relays to prevent the microprocessor from being affected.
Diagnostic LEDs:
L ON = board on 230/400 V voltage and F1, F2, F3 fuses all right
L0 OFF =
pedestrian mode, it switches on by any pedestrian pulse
st
L1 ON = 1
pair photocells not obstructed
L4 OFF = open, it switches on by any open pulse
L5 OFF = close, it switches on by any close pulse
L6 ON = stop, it switches off by any stop pulse
L7 OFF = radio, it switches on by any pulse from the transmitter/radio contact
L8 ON = it switches off when Fc.C. (limit switch closing = L-sw.C) is engaged, M1
L10 ON = it switches off when Fc.A. (limit switch opening = L-sw.O) is engaged, M1
L30 ON = it switches off when Fc.C. (limit switch closing = L-sw.C) is engaged, M2
L31 ON = it switches off when Fc.A. (limit switch opening = L-sw.O) is engaged, M2
L33 ON = safety edge protecting closing not obstructed
L34 ON = safety edge or photocell protecting opening not obstructed
nd
L35 ON = 2
pair photocells not obstructed
IN CASE OF FAILURE PLEASE MAKE SURE THAT:
- Power supply to the electronic control box is 230/400 V ±10%.
- Power supply to the electric motor is 230/400 V ±10%.
- All of the fuses is all right.
- The photocell contacts are closed.
- No voltage drop has occurred from the Elpro board to the electric motor.
- All of the NC contacts of the control board are all right.
