9 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. Figure 5 - Alarm Contact 1 COM NC NO 2 3 Alarm Relay Rating 120 VAC.5 A 30 VDC 1A 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. Table 3 - List of conditions and indications Condition Description Red Light Status Green Light Status Amber Light Status Inverter Operation Status Normal 88.5% < VLINE < 110% of Nominal Off On Off Off Sag Event VLINE < 88.5% while MiniDySC is correcting Off On Off Running Runtime Exceeded Cumulative runtime exceeded Off On Flashing Inhibited Normal Mode, Static Switch Overload Continuous Load current > 150% On Off Off Inhibited Inverter Run Mode, Output Over current Load current > 150% for 3 cycles Off On Flashing Inhibited Refer to Run Time specifications in Technical Specifications on page 11 See Static Switch Maximum Current specifications in Technical Specifications on page 11 If red LED is on, the output of the MiniDySC is inhibited and power needs to be cycled. If the problem reoccurs, the MiniDySC is overloaded. On, provided output is within normal range 88.5%< VLINE <110%. Check Alarm Codes Rockwell Automation Publication 1608N-UM001B-EN-P - May

10 Chapter 2 Operation Alarm Codes Alarm LED Flash Sequence Alarm Name Number of Flashes While the MiniDySC is in the alarm state due to a non-fatal alarm, the amber LED will flash the alarm code sequence at 1Hz where the number of flashes equals the alarm code. There is a two-second delay, after which the code will repeat if the error condition persists. This group of alarms are those that the user can act to correct, such as an overload or input over-voltage. Some alarms cannot be corrected by user action. These alarms may require service by a qualified technician. For such alarms the amber LED will flash continuously at a faster 6 Hz rate. Table 4 - Alarm LED Flash Descriptions Alarm Description Alarm Resolution Inverter Run Time out MiniDySC inverter had a total cumulative runtime of more than rated. No action is needed 3 Inverter Limit Cycle Timeout Power was re-applied more than once within a 58 second period. No action is needed Overload Static Switch Over -Temperature 4 Inverter inhibited because load current exceeded maximum rating. Static switch heatsink temperature was greater than maximum rating. DC Bus Over-Voltage 5 Positive or negative half of DC bus voltage exceeded maximum rating. Reduce the load Verify ambient temperature is within specification Check for dirty or obstructed air vents Check fan is operating (500VA and 750VA only) Verify line voltage is within ratings.
