Operation Chapter 2
Alarm Contact Connections
• The alarm contact will change states during any alarm condition. When the
alarm condition has cleared, the alarm relay will return to its normal state.
• Terminal block pin numbers and Alarm contact ratings are shown in Figure 5
Operation is as follows:
– Normal Line Condition: pin 1 connects to pin 3.
– Alarm Condition: pin 1 connects to pin 2.
– Power Off Condition: pin 1 connects to pin 2.

Power Switch
The service disconnect or the external branch circuit breaker may be used as a
master on/off switch.
Operating Indicators
• When power is switched on, the Green light (Normal) on the front of the
MiniDySC will be lighted. The green light indicates that the output voltage
is within a normal range of -13% to +10% of nominal. This indicator will
also be on during sag correction events since the MiniDySC will be
maintaining the output voltage.
• The Amber light (Alarm) flashes when the MiniDySC correction function
is inhibited. See Alarm Codes section below. The MiniDySC will resume its
corrective function and the flashing light will turn off when the alarm
condition has ceased. In a flashing amber light condition, the MiniDySC
will continue to pass the utility power to the load via the static switch.
• The Red light will be on when the Static switch is inhibited due to an
overload condition. The MiniDySC will open the output. Power will need to
be cycled to reset the MiniDySC.
