Product Configuration & Setup

Proper installation and configuration of the Rolf Janssen BM-06 Operation Switch with DBU-06 Wire Break Monitor are essential to achieving reliable operation and maximizing the safety benefits of the wire break detection capability. The following guidelines provide a framework for successful deployment in typical industrial applications.

The unit is designed for installation in a standard 19-inch equipment rack, occupying a defined number of rack units depending on its configuration. Before installation, verify that the rack has adequate depth to accommodate the unit and provide clearance for rear-panel wiring. The unit should be mounted at a height that is comfortable for operator access to the front panel controls, typically between 800mm and 1600mm from the floor in standing-height installations.

Power supply connections should be made using the rear-panel terminal block, observing correct polarity for the 24V DC input. The power supply should be rated to deliver the maximum current drawn by the unit under all operating conditions, including alarm states where indicator lamps and relay outputs may be activated simultaneously. Use of a regulated power supply is recommended to prevent voltage fluctuations from affecting the sensitivity of the wire break detection circuits.

The wire break monitoring channels are connected via dedicated terminal blocks on the rear panel. Each monitored circuit should be wired as a closed loop, with the DBU-06 module injecting a small test current and measuring the resulting loop resistance. If the loop is broken at any point, the test current ceases to flow, and the module registers a fault condition. The monitoring sensitivity may be adjustable to accommodate different circuit lengths and wire gauges; consult the product documentation for the specific adjustment procedure applicable to your unit.

Alarm outputs from the DBU-06 should be connected to the supervisory system in accordance with the facility's alarm management philosophy. Typically, wire break alarms are configured as fault-level notifications that require operator acknowledgment and maintenance intervention to clear. In safety-critical applications, these alarms may be wired into an emergency shutdown or safety instrumented system, where they contribute to the overall safety integrity level of the protected process.

Regular testing of the wire break monitoring function should be performed as part of the facility's preventive maintenance program. Most wire break monitors include a test facility that simulates a break condition without actually disconnecting any wiring, allowing verification of the complete alarm chain from detection through notification. This testing should be documented and any discrepancies investigated promptly to ensure the continued reliability of the monitoring system.
