1.6.7 Control in signal properties
Control In
There are 32 control inputs which can be activated via the relay menu, ‘hotkeys’ or via rear
communications. Depending on the programmed setting i.e. latched or pulsed, an associated
DDB signal will be activated in PSL when a control input is operated.
For example operate control input 1 to assert DDB 800 in the PSL.
1.6.8 Function key properties
Function Key
Each function key can be selected and used for programming in PSL. Activation of the
function key will drive an associated DDB signal and the DDB signal will remain active
depending on the programmed setting i.e. toggled or normal. Toggled mode means the DDB
signal will remain latched or unlatched on key press and normal means the DDB will only be
active for the duration of the key press.
For example operate function key 1 to assert DDB 712 in the PSL.
1.6.9 Fault recorder trigger properties
Fault Record Trigger
The fault recording facility can be activated, by driving the fault recorder trigger DDB signal.
For example assert DDB 144 to activate the fault recording in the PSL.

1.6.10 LED signal properties
LED
All programmable LEDs will drive associated DDB signal when the LED is activated.
For example DDB 652 will be asserted when LED 7 is activated.
1.6.11 Contact signal properties
Contact Signal
All relay output contacts will drive associated DDB signal when the output contact is
activated.
For example DDB 009 will be asserted when output R10 is activated.
