Description
AC System
These settings are used to detail the type of AC system to which the module is connected:
3 phase 4 wire, 1 phase 2 wire, 2 phase 3 wire – L1-L2, 2 phase 3 wire – L1-L3, 3 phase 3
wire, 3 phase 4 wire delta
This list is not exhaustive. DSE reserve the right to add to this list as part of our policy of

sequence relay
= Mains phase rotation is not checked.
= A ‘mains failure’ situation is generated if the phase rotation is not as configured.
Breaker Control Timer before the fail to close alarm is activated
Parameter Description
VT Fitted
= The voltage sensing to the controller is direct from the mains
= The voltage sensing to the controller is via Voltage Transformers (VTs or PTs)
This is used to step down the supplied voltage to be within the modules controller voltage
specification.
By entering the Primary and Secondary voltages of the transformer, the controller will
display the Primary voltage rather than the actual measured voltage.
This is typically used to interface the DSE module to high voltage systems (ie 11kV) but
can also be used on systems such as 600V ph-ph.
