10.4 AS1668 Fan Control Card Programming
The 4100U-S1 can be installed with an ME0456 AS1668 fan control module which is
programmed as a 4100-1284 8 x Button and 16 x LED module.
Follow the 4100-1284 programming as described in Section 7.3, except for the
Point
Editing
tab which differs from the standard zone programming and is described here.
10.4.1
Switch Configuration
The
Switch
configuration couples each of the fan
‟s rotary switch states to a pseudo point
that reflects the current fan state. The fan
‟s pseudo points definition is built-in as part of the
configuration template. These pseudo points can be monitored via the panel
‟s display
screen and referred to from the online executable via custom controls.
Each fan uses 2 X
Switch
entries with a pseudo
point for each entry that is
set whenever the entry
state is reached:
1. In
„Manual Start‟
state
–The
„Manual Start‟
pseudo point is set
and the
„Manual
Stop
‟ pseudo point
is cleared.
2. In
„Manual Stop‟
state
–The
„Manual Stop‟
pseudo point is set
and the
„Manual
Start
‟ pseudo point
is cleared.
When in
„Auto‟
position both the
„Manual Start‟ and the „Manual Stop‟ pseudo points are cleared.
In the
Mode
text box enter „PBT‟.
In the
Reference Address
text box enter the matching pseudo point (P1201 - P1264).
Highlight the next line to configure the next entry with the adjacent pseudo point.
