Power - 3Vdc (1 x CR2032)
Standby current consumption - < 1uA
Transmitting current consumption 16mA @ + 10dBm
Range - 50m

Features
The Symbolic Instruments v.1 roller garage door panel has 9 terminals for AC control:
Live, Neutral, and Earth
Motor: Two directions, Neutral and Earth
Two terminals for an external bulkhead light (230V)
There are 12 terminals for DC control:
Three terminals for the OSE safety edge control
One terminal for the magnet sensor (part of the OSE system)
Four terminals for the external switch (12v / Up / Down / Stop)
Two terminals for safety brake or emergency stop circuit
Two terminals for an optional alarm
The light and the alarm are both treated as add-ons and not part of the module.
Firmware and Programmable Chip
The control panel is run on a removable microchip which allows easy re-programming by Powell Doors engineers. As standard, the board carries out the following functions:
Control of a tubular motor by signal from a remote control handset
8 single channel remotes can be memorised
Optical safety edge (OSE) and photocell (PEC) safety accessories
Control by enclosure mounted up / down / stop buttons
Terminals for external key switch
Runtimer to prevent limit switch failure
Autoclose, with timed close cycle
Safety device on / off
Current surge detect / stall detection
Full automatic / semi-automatic / deadman operation options
Alarm on / off


Status display and progamming by encoder
Modifications to the run timer, safety, etc., are carried out on site with the encoder knob. This scheme follows the classic GfA Elektromaten system for industrial doors. Fault finding and diagnostics become easy when the seven-segment illuminated display shows the status of the door, and any Fault or running conditions.
Safety device
The panel is supplied with an Optical Safety Edge system (OSE) which is to be installed inside the roller garage door weather seal. Symbolic Instruments supply their own Tx / Rx (send and receive) plugs for the infra-red beam, and the safety edge slave box, with PUR helical curled cable. Without the safety edge, the door can be run in dead man mode. The panel can also be fitted with a Photoelectric Cell system (PEC) for additional protection.
