DGC-MK2 controller Version 2 DGC-MK2 controller Version 1 For the purposes of these notes, Version 1 and Version 2 units are identical. Download the manual for full operational details. INTRODUCTION The DGC-MK2 is a microprocessor based circuit module. It provides interfacing and logic functions to control a standard motorized gate or door. For high-speed gates or doors, see the DGC-MK4 controller. As part of an access control system the DGC-MK2 will simplify programming and installation, often eliminating the need for an additional PLC or logic controller. It will look to the access control system like a simple pedestrian door. In a domestic or stand-alone situation the DGC_MK2 can easily be interfaced to a remote control receiver, alarm panel or home automation system. In most cases the DGC-MK2 will completely replace the relay and timer logic, and complex wiring of existing gate and door control cabinets. The DGC-MK2 can be mounted in a cabinet with other control equipment or be mounted on its own on a wall adjacent to the gate or door being controlled. Contact PMB for details of the turnstile mode of operation. FEATURES IDEAL FOR DOMESTIC AND COMMERCIAL GATES AND GARAGE DOORS. SIMPLE TO INSTALL, SETUP AND USE. NO PROGRAMMING EQUIPMENT REQUIRED. SIMPLE CONTROL INTERFACING. SUPPORTS MULTIPLE (parallel) CONTROL POINTS. MANUAL OR AUTOMATIC (timed) CLOSING. PEDESTRIAN FUNCTION (part open). FULLY PROGRAMMABLE TIME DELAYS. REMEMBERS TIME DELAY SETTINGS DURING POWER FAILURE. PROVIDES AUTOMATIC SAFETY/SECURITY LIGHTING CONTROL. (considerable power saving possible with lighting control). FULL SAFETY BEAM SUPPORT LOGIC. MOTOR OVERLOAD MONITORING. ONBOARD 230V SINGLE PHASE MOTOR AND LIGHT SWITCHING. SUPPORTS DUAL SPEED DRIVE (with external speed controller). 4 CONTROL INPUTS (open, close, stop, light). 2 SAFETY INPUTS (safety beam, motor overload). 4 CONTROL OUTPUTS (open, close, brake, light). 3 STATUS OUTPUTS (operating, closed, alarm). OUTPUTS CAN DRIVE ADDITIONAL MOTOR SWITCHING RELAYS. EASILY MOUNTED MODULE. OPTIONAL WEATHERPROOF PLASTIC ENCLOSURE. REQUIRES SINGLE 12 Volt OR 24 Volt DC, 150 mA POWER SUPPLY. FULL WATCHDOG AND PROCESSOR SUPERVISION. IMPORTANT NOTICE If you are at all unsure about the installation or operation of gates, doors or the DGC_MK2 controller, seek advice. There are two basic types of gate control: Simple timed operation, no reliance on limit switches. Limit switch based operation. The simple sort (1 above) can be applied to slow moving gates or doors in some situations only. PMB does not recommend this type of control. The second type of control relies on limit switches with secondary timing. This ensures that the gate is always cycled between two known points, closed and open. Unfortunately, this requires the limit switches to be in good working order. A failure to operate correctly will usually be the result of a failed or miss-aligned limit switch. Bigger is not always better. Larger switches tend to have silver contacts. These are not the best for low currents, gold contacts should be chosen.
