SECTION 5 – SETTING THE BIT SWITCH ON IAC400/600 ONLY
The bit switch is used for setting both the unit's address and it's preset
application. Which function is currently being performed is defined by
bit switch 7.
Bit switch 7 OFF - Preset set on bits 1-6
Bit switch 7 ON - Address set on bits 1-6
To enter either the address or preset into the controller toggle bit switch
8 from OFF to ON to OFF again. This causes the controller to reset
itself and it is only during such initialization that the preset/address is
read from the bit switch. They may be changed via satchsoft at
anytime.
When the controller is to use one of the predefined presets, always
leave it with the relevant preset selected on the bit switch. This ensures
that in the event of memory corruption the controller can reload the
defaults applicable to the appropriate preset.
CUSTOM COMPUTER CONFIGURATION
1. IACs should be set to preset 0.
SETTING THE CONTROLLER PRESET APPLICATION
1. Ensure bit switches 7 and 8 are both OFF.
2. Set the preset application number you require using bit switches 1
to 6.
Note: Preset 0 is set by setting bit switches 1 to 6 OFF.
3. Set bit switch 8 to ON.
4. Set bit switch 8 to OFF. This will enter the preset application
number into the controller.
If you are to download your application from a computer using Satchnet
then you must select preset 0 from the bit switch. This will ensure that
in the event of a power failure, the software preset will not be
overwritten on subsequent power-up.
Example:- Loading Preset 3.
SETTING THE CONTROLLER ADDRESS
1. Ensure switch 7 is ON and switch 8 is OFF.
2. Set the address for the controller using bit switches 1 to 6.
3. Set bit switch 8 to ON.
4. Set bit switch 8 to OFF.
