Microprocessor Module Replacement

for Single-Zone Leak Monitors

Instruction Manual 3015-5550

1. Scope

This instruction manual describes how to replace or upgrade the microprocessor module in your “new style” Single-Zone

leak monitoring equipment (with serial numbers having the format “NU-xxxx”). It is assumed that you are familiar with the

operation of the appropriate monitor. If necessary, refer to the instructions for detailed operation and maintenance

information for each Single-Zone model.

The replacement process covers the following topics:

• Items Required

• Retrieving Current Configuration Data

• Preparation

• Microprocessor Module Removal

• Installing the New Microprocessor Module

• Configuration.

2. Items Required

• Replacement Microprocessor Module Kit (P/N: 3015-5549)

• Medium Phillips head screwdriver

• Medium standard slotted screwdriver

• Wrench for lock nut

IMPORTANT: Failure to comply with these instructions may void the warranty.

3. Retrieving Current Configuration Data

Your Single-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 verified and (if necessary) reloaded

after the new microprocessor module is installed. Use the table in Section 7 to record current parameter settings.

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.

4. Preparation

Prepare to remove the old microprocessor module by following the steps below.

a. Disconnect power to the leak monitor and confirm that no power is present.
