Rotary - Trunnions with Scales - Compatibility Solution

AD0366

Introduction

Identify the type of scale in your trunnion:

  • Trunnions built from 2011 (when scales were introduced) to September 2016 use a scale that requires 12VDC power
  • Trunnions built from October 2016 to mid-January 2017 require 5VDC power.
  • Trunnions built after mid-January 2017 work with either 5VDC or 12VDC power. These can be identified by the gray connector on the scale cable.

Applicable to the following kits:

  • 93-2683: CABLE KIT 5/12VDC ROTARY SCALE FEEDBACK TO 12VDC CONTROL

Compatibility Solution

1

Identify the voltage supplied by the I/O PCB:

Look at the label on the cable that connects the scale connector to the I/O PCB.

All Classic Haas Control (CHC) machines with the 32-10049 cable are configured for trunnions with 5VDC scales. Install the 32-10053 (not included in the kit 92-2863) to configure the machine for 12VDC scales.

NGC machines with the 32-10053 cable are configures fro trunnions with 12VDC scales.

Solution:

The best solution is to configure the machine and the trunnion with 12VDC power. This maintains compatibility with the past, current, and future equipment.

All CHC machines are configured for 12VDC.

If the NGC machine is configured fro 5VDC, install the 32-10053 cable ( not included in kit 93-2683) to configure it for 12VDC.

Any trunnion can be made compatible with a 12VDC machine by installing the 32-10055 rotary cable. the 32-10055 cable can be identified by the grey connector [1] on the scale cable.

3

Do this step if the trunnion has a 12VDC scale installed.

The 32-10055 cable has a flying connector [1] inside of the rotary enclosure. Plug the 33-10088 jumper [2] to the flying connector as shown.

4

Do this step if the trunnion has a 5VDC scale installed.

The 32-10055 able has a flying connector [1] inside of the rotary enclosure. Plug in the 32-10057 voltage reducer [2] to the flying connector as shown. The trunnion can now be plugged into any 12VDC configured machine.
