MIC400 Series Camera Installation and Operation Manual
10.A washer drive is provided on this power supply, a mains rated relay is fitted and
11.Once connected the washer drive can be tested using the red SW1 which should activate the pump. This will allow for priming the plumbing. When pressed the LED, (LED3) next to the washer switch should illuminate. The LED will also illuminate in response to telemetry commands to switch the washer on. The Red LED on the washer PCB will illuminate when the Washer function is selected at the control room end. Note that the software in the camera prevents the washer from being run more than 10 seconds continuously. (This is to prevent the washer bottle from being inadvertently emptied. The red button on the washer drive card can be used to both test the washer operation and to prime the washer pump.
12.When wiring is complete, apply power & check the all six (6) LED’s are lit. LED1 and LED2 when light show that 15v AC is available from the power supply (i.e. the supply fuses are intact. There is no indication of the operation of the Telemetry lines as this would increase the load on these lines reducing the number of cameras that can be driven by a single telemetry spur.
LED 3 illuminates when the washer drive relay is selected to on.
LED 4 monitors the internally generated +5v rail used to drive the alarm interface circuits around HD2. This +5v supply is not available externally. LED 5 illuminates when the IR supply is selected to on by the camera telemetry.
LED 6 Pulses on/off when the MIC400 camera is correctly configured to operate with the IR power supply.
13.When satisfied the PSU is functioning correctly,

MIC-IR-12PSU
The power supply operates from a 12v DC source typically between 10.5v and 15v DC, for example, a lead acid battery. The PSU provides power to a MIC400 camera at 18v DC nominally.
Current draw:
For the camera
Max current draw with camera moving, wiper on and IR illuminators on is 3.8Amps.
Dimensions
Power supply enclosure: - 260mm (W) x 90mm (H) x 120 (D)
A weather resistant (IP66) box prefitted with four cable glands.
A second isolated power supply for driving the IR illuminators, the operation of this power supply is controlled by the camera itself via telemetry commands received from the control room. The power supply operates with dual illuminators. This drive is a constant current drive which automatically configures itself for IR lamp operation. There are no adjustable items within the power supply except for the three links discussed below.
Screw termination of all third party cables into and out of the box.
Correct video termination for the camera coaxial cable.
The power supply provides a circuit for operating a 12v driven washer drive pump and reservoir system.
The power supply also supports 4 off volt free alarm contact inputs, which can be made to activate presets within the camera but always notifies the control system of the status of these alarms.
Earthing; the power supply and all equipment connected to it is earthed to the
