1. Warnings and legal information
Legal information and responsibility
DEIF takes no responsibility for installation or operation of the generator set. If there is any doubt
about how to install or operate the generator set controlled by the unit, the company responsible
for the installation or the operation of the set must be contacted.
Electrostatic discharge awareness
Sufficient care must be taken to protect the terminals against static discharges during the
installation. Once the unit is installed and connected, these precautions are no longer necessary.
Safety issues
Installing the unit implies work with dangerous currents and voltages. Therefore, the installation
should only be carried out by authorised personnel who understand the risks involved in working
with live electrical equipment.
Definitions
Throughout this document a number of notes and warnings will be presented. To ensure that these
are noticed, they will be highlighted in order to separate them from the general text.
Notes
Warning
The notes provide general information which will be helpful for the reader to
bear in mind.
The warnings indicate a potentially dangerous situation which could result in
death, personal injury or damaged equipment, if certain guidelines are not
followed.
Be aware of the hazardous live currents and voltages. Do not touch any AC
measurement inputs as this could lead to injury or death.
The units are not to be opened by unauthorised personnel. If opened anyway, the
warranty will be lost.

2. Description of option
C1 option
Option C1 is a software option and therefore not related to any hardware apart from the
standard-installed hardware. Option C1 is a mix of frequency, voltage, overload, overcurrent,
unbalance alarms and reactive power import/export protections as follows:
Protection ANSI no.
Overvoltage 59
Undervoltage 27
Overfrequency 81
Underfrequency 81
Overload 32
Fast overcurrent 50/51
Current unbalance 60
Voltage asymmetry 60
Loss of excitation (reactive power import) 40
Overexcitation (reactive power export) 40

3. Functional descriptions
Voltage and frequency
Voltage and frequency is set in % of nominal generator value. The delay settings are all of the
definite time type, meaning that a set point and time is selected.
If the function is e.g. overvoltage, then the timer will be activated, if the set point is exceeded. If
the voltage value goes below the set point value before the timer runs out, then the timer will be
stopped and reset.

value
When the timer runs out, the output is activated. The total delay will be the delay setting + the
reaction time.
Alarm inhibit
Some of the alarms included in the option C1 can be inhibited in order to avoid nuisance alarms
during controlled conditions such as start/stop of the gen-set and breaker operations.
For general information about the inhibit function, please refer to the Designer’s
Reference Handbook.

4. Parameter list
Parameter table description
The table consists of the following possible adjustments:
Set point: The alarm set point is adjusted in the set point menu. The setting is in
Hz/sec.
Timer: The timer setting indicates the duration of the period between the alarm
situation and the alarm occurrence.
Relay output A: A relay can be activated by the output A.
Relay output B: A relay can be activated by the output B.
Enable: The alarm can be activated or deactivated. ON means always activated,
RUN means that the alarm has run status. This means it is activated when
the running signal is present.
