ISSUE RESOLUTION
When there is a power outage, my entire
SmartRow shuts down.
• Make sure the control panel logic is fed from a double-conversion UPS power source. If
the control logic looses power, it will appear as if an EPO is pressed.
• The UPS(s) connected to the system may give indications of an EPO being pressed,
which also indicates a loss in control-logic power and improper connection to the system.
• Call 800-222-5877, option #1.
The cooling unit(s), UPS(s),
and the Control Panel & Fire Suppression
system will not turn on.
• Make sure that the CB1 and CB2 in the top, right-hand corner of the Control Panel and Fire
Suppression module are closed (ON). See Figure 7.2 on page 62, for the locations.
These provide power to the control-logic circuitry.
• Ensure that the two 15-A breakers supplied in the Load Distribution center are closed (ON)
as they provide power to the fire suppression panel and the emergency ventilation fans
• Turn EPO Override timer beyond the ½-hour position and restart the UPS.
• If the SmartRow DCR is powered by a stand-alone, 3-phase Liebert UPS and will not
restart, put the UPS in bypass and restart the remaining equipment.
• Call 800-543-2738 for assistance in putting the UPS in bypass and for service support.
The fire suppression panel is alarming.
• Reference the Troubleshooting section 6.3 of the Fike SHP Pro Product Manual to identify
the type of event triggering the alarm.
• Call your local Fike fire-suppression representative with the details regarding the event for
proper support of your system.
When the EPO is pressed the cooling units
do not shutdown.
• Make sure that the 4-pin HVAC fault / Emergency Ventilation Fan Control, Thermal-unit
Shutdown Connector Cable (P2) is connected to its low -voltage PDX/PCW receptacle.
• See Locate and Install 4-pin HVAC Fault/Emergency Fan Control,
Thermal-unit Shutdown Connector Cable (P2) on page 41 for additional details.
When a cooling unit shuts off
and the Emergency Ventilation Fans do not
activate.
• Make sure that the 4-pin HVAC fault / Emergency Ventilation Fan Control, Thermal-unit

• See Locate and Install 4-pin HVAC Fault/Emergency Fan Control,
Thermal-unit Shutdown Connector Cable (P2) on page 41 for additional details.
• Check to see if the load-distribution-center breaker that feeds the emergency-fan circuit is
closed (ON).
• Check to make sure that the return-air-temperature sensor is properly connected as
documented in
Connect Return-temperature Thermostat,
the L5-20 Receptacle and the Smoke Detector on page 38.
