1.3.9 Control input configuration
The control inputs function as software switches that can be set or reset either locally or
remotely. These inputs can be used to trigger any function that they are connected to as
part of the PSL.

Setting to allow the control inputs to be individually assigned to the “Hotkey” menu by
setting ‘1’ in the appropriate bit in the “Hotkey Enabled” cell. The hotkey menu allows the
control inputs to be set, reset or pulsed without the need to enter the “CONTROL INPUTS”
column
Control Input 1 Latched Latched, Pulsed
Configures the control inputs as either ‘latched’ or ‘pulsed’. A latched control input will
remain in the set state until a reset command is given, either by the menu or the serial
communications. A pulsed control input, however, will remain energized for 10ms after the
set command is given and will then reset automatically (i.e. no reset command required).
Ctrl Command 1 Set/Reset
Set/Reset, In/Out, Enabled/Disabled,
On/Off
Allows the SET / RESET text, displayed in the hotkey menu, to be changed to something
more suitable for the application of an individual control input, such as “ON / OFF”, “IN /
OUT” etc.
Control Input 2 to 32 Latched Latched, Pulsed
Configures the control inputs as either ‘latched’ or ‘pulsed’.
