Multifunctional Gauge Combination Module

Summary

ZDZ1 multifunctional gauge combination module is composed of double-pointer speed gauge, slot-type ammeter, state indicator light, emergency brake button, signal transmission cable. Installed in the control console, it is an important set, showing train operating parameters, equipment operation state, and other related information. Depending on the combined module structure, it is endowed with the following advantages: convenient installation, visual display, integral beatification, good reliability.

Function

1. Measure and display the instant speed and limited speed of running locomotive.

2. Measure important operation parameters of locomotive. (See appendix)

3. Display the operation state of equipment in locomotive. (See appendix)

4. Electric locomotive have emergency brake button, while diesel locomotive don't.

Technical Parameter of Gauge Module

The technical parameter of gauge module is composed of three separate technical parameters of double-pointer speed gauge, slot-type ammeter, and state indicator.

Operation method  

1. Installation

Connect the ammeter terminals and connect plugs, put the gauge module into the installation hole of control console, fix the holding screws.

2. Lighting adjustment

Brightness stepless adjustment of indicator light

Brightness adjustment:When the indicator light is turned on, press the brightness button ,when the light gets brighter,leave the button and the brightness will be kept;press the brightness button,when the light gets darker,leave the button and the brightness will be kept

Brightness self-check:Press the button  &  at same time, the indicator light will flicker at the brightest lightness.

Brightness holding:The brightness will be kept after power-off.

Maintenance

1. When install the 48-pin and 9-pin socket, fix the locking screw tightly

2. The gauge module has the capacity of 120% overload, but the upper limit value in dial should not be exceeded.

3. Every 3~6 months the gauge module have to be checked in order to ensure the accuracy and the quality of indicator light.

4. Pay attention to dust-proof, damp-proof, and quake-proof for gauge module when not using. The module should be kept in storeroom with ambient temperature 0~40℃ and relative humidity 85%, keeping away from caustic and hazardous gas and substance. If not use the module for over three months, it should be electrified each three months in order to keep the performance of electric components during effective storage life.
