MS 1 Stair lift Controller
MS 2 Ancillary Interface

The board has been built to meet the requirements of both BS 5776:1996 and ISO 9386-2 for Stair lifts.

The MS 1 does not have the CSE 126 Ancillary interface built in, it has the option to plug-in an MS 2 which provides the functionality. This is ideally suited to customers who provide a small percentage of stair lifts with ancillary functionality.

Features integrated on to the board:
• Four-quadrant control
• Dual redundant safety system
• 3 Stage - Battery management
• Full fault diagnosis in conjunction with the CSE 127
• Short circuit proof loom interface
• PC Diagnostic software through the fully isolated CSE 128
• 8-way DIP Switch providing customization:
- Left hand / Right hand select
- Powered Hinge Support (CSE 126 required)
- Powered Platform Support (CSE 126 required)
- 5 spare for customer specification
• Inputs available for automatically slowing the lift through an inside curve
