Microprocessor Module Replacement Kit

for Multi-Zone Leak Monitors

Instruction Manual

1. Scope

The Bacharach Multi-Zone family of fixed point monitors is designed for easy maintenance and enhancement. One

element of that design is the ability to replace system programming (firmware) with a simple plug-in microprocessor

module, minimizing downtime.

This instruction manual describes how to replace or upgrade the microprocessor module in your Multi-Zone leak

monitoring equipment. It is assumed that the user is familiar with the operation of the appropriate monitor. If necessary,

refer to the instructions for detailed operation and maintenance information for each Multi-Zone model.

2. Items Required

Replacement Microprocessor Module Kit (P/N: 3015-5546)

Medium Phillips head screwdriver

Medium standard slotted screwdriver

Wrench for lock nut

CAUTION

Failure to comply with these instructions may void the warranty.

3. Retrieving Setup and Configuration Data

Your Multi-Zone monitor has been configured for your specific installation. Prior to beginning this procedure it is highly

recommended to collect setup and configuration data from your monitor so it can be reloaded after the new

microprocessor module is installed. Use the table that follows to record the necessary parameters.

NOTE:

Note that a system hardware failure may make these values inaccessible or may reset them to default values

in a “fail safe” mode. If the values are not accessible or do not match your installation, you should skip this

step. If you need assistance, contact Bacharach Technical Support at (800) 736-4666 or (724) 334-5000.

NOTE:

The node address of your Multi-Zone device can be found on page 2 of the System Setup Screen.
