4 OPERATING INSTRUCTIONS
4.1 INTRODUCTION
After installation (as described in Chapter 3), normal operation of the DRB-25 is achieved by applying power
to the DRB-25 and switching on the rear panel power switch and the Power Supply Modules.
The DRB-25 Modules will perform self-test diagnostics after power is applied. Visual indicators on the
module front panels will convey the status of the DRB-25 to the Operator. If any of these visual indicators
show an error or fault code, simple faultfinding procedures may identify the problem and suggest an
immediate solution.
If operational checks reveal a fault in DRB-25 equipment, it may be necessary to replace it. Removal of
equipment is the reverse of the installation procedure described in Chapter 3. Any faulty items should be
carefully packaged and sent to an authorized repair center.
If faults are not corrected by substituting equipment at an operational level, contact the supplier or its
representative.
Additional connectors on the front and back panels of selected equipment allow maintenance personnel to
access functions for system configuration, operational statistics and faultfinding.
4.2 SWITCHES
There are two types of switches on the front panels of the DRB-25: power and reset switches.
If an AC supply is used with the DRB-25, there is a master power supply switch on the rear of the unit which
should be turned on first. The power switches on the front panel of the Power Supply Modules are switched
on next.
Recessed reset switches on the Transceiver, Controller and Interface Modules (optional) allow the equipment
to be reset. Table 4-1 describes each reset switch and its function.
Table 4-1 Reset Switches
Equipment Reset function
Interface Module Resets all modules (accessed from rear )
Controller Module Resets all modules (accessed from front)
Transceiver Module Resets the Transceiver Module (accessed from front)
4.3 APPLYING POWER
Perform the following final checks before applying power:
1. Check that the ground wires are connected to the DRB-25 primary ground from an external ground point.
2. Check that all equipment and connections are secure.
3. Ensure the power cable to the DRB-25 is plugged in securely and switch power on.
