12V dc or 24V ac operation without any wiring changes. Its wider voltage range also provides protection from voltage surge, transient spikes, and reverse voltage. The EX27 is available in several models to meet individual requirements or specific needs. See the Light. Get the Picture. ™...
Inspect the equipment thoroughly to ensure nothing was damaged in transit. Contact BOSCH Service Center if a problem is noted, see the rear page of this booklet for contact numbers. PARTS LIST (items supplied with unit)
INITIAL PREPARATIONS Determine the operating voltage at the installation site. All cameras have been tested prior to shipment. Select a suitable location that is protected from accidental damage, tampering, and environmental conditions exceeding the camera’s specifications. Caution: The selected mounting location should not place the camera in a situation where its environmental specifications could be exceeded.
GUIDELINES Three basic requirements must be met before the EX27 can be installed. 1. Voltage Setting 2. Camera Wiring & Settings 3. Video Auto-Iris, CS-mount Lens Sections 1 to 3 will guide the installer through...
1. VOLTAGE SETTING The camera unit is pre-connected with an electrically isolated power board for 24V ac or 12V dc operation with no wiring change or wiring polarity. See diagram below for wiring details. Note: Input voltage is 10.5VDC to 40VDC for DC input. The AC input range is 12VAC to 28VAC.
2. LENS SETTING The following steps show the installer how to access the camera board and the camera lens. Step 2.1 - Disconnect the power source to the camera and the video signal at the BNC connector. Step 2.2 - Remove the four cap screws with a 3mm Allen key.

Vari Focal Lens Adjustments Loosen the lens set screws for focus/zoom adjustments. The setscrew marked N ←→ ∞ is used for image focus. The setscrew marked T←→ W is used for telephoto or wide-angle settings. Re-tighten the setscrews after focus adjustments have been completed.

Use a Neutral Density filter or Infra-Red Pass filter to cover the lens during focusing to simulate low light conditions on scene for correct 24-hour focusing. For camera with vari- focal lens, the camera should be focused with the lens iris fully opened to simulate the worst possible depth of field.
4. TROUBLESHOOTING GUIDE PROBLEM POSSIBLE LIKELY CAUSE SOLUTION No Video 1. Power Supply: -Connections…. Check input power connections at the cable leads Check for loose wires. -Voltage Range... If connected to DC, check voltage input range of 10.5 - 40 V. If connected to AC, check input voltage range of 12 –...
If still no video, connect the camera directly to the monitor. Check the video signal. If okay, the problem is with the interconnections. If still no video, BOSCH contact Service Center. See rear page of this manual for contact information. _________________...
