Tyco 4100U - Manual (Page 142)

10-4
ME0456 is a 4100U style Switch/LED display module specifically designed for fan
control. It complies with the requirements of AS1668.1, 1998. It has rotary switches and
LEDs for 4 fans. In order to accommodate the required rotary switches, the front plate is
joggled forward so that it protrudes through the trim.
The Fan Control switch positions of ON, AUTO and OFF, as per the standard, are
permanently marked on the faceplate label.
The labeling of the LEDs, ON, FLT, and OFF is marked on the removable fan name label
card, LB0605, supplied with the module.
The card may be reversed and different LED labelling used, e.g. as required for damper
controls.
The name area accommodates 3 rows of 6 letters at 5mm.
A “soft” version of this label is available on the TSP website as LB0605. This template
allows entry of the fan name on a PC for local printing. LED names may also be revised.
The Fan Control module mounts to the frame of the 4100U Expansion bay door, from the
front, by the studs on the module with the nuts and washers provided.
Connection from “Out” of the adjacent Switch/LED module (or 64/64 Controller if it is
the first module on that Controller) to “In” on the module is by the flat flexible cable
provided (SX0039).
The Module is programmed as a standard 8 Switch/16 LED module. Up to 4 can be
driven by one 64/64 Switch/LED Controller.
Each fan control with one rotary switch uses two of the 8 “switches”, and 3 of the 16
LEDs of an 8 Switch/16 LED module as per Table 1. The other 4 LEDs are not fitted so
must not be programmed.
