580J

NOTE: All troubles are latched by the duct smoke detector. The trouble condition must be cleared and then the duct smoke detector must be reset in order to restore it to the normal state.

Resetting Alarm and Trouble Condition Trips:

Manual reset is required to restore smoke detector systems to Normal operation. For installations using two sensors, the duct smoke detector does not differentiate which sensor signals an alarm or trouble condition. Check each sensor for Alarm or Trouble status (indicated by LED). Clear the condition that has generated the trip at this sensor. Then reset the sensor by pressing and holding the reset button (on the side) for 2 seconds. Verify that the sensor’s Alarm and Trouble LEDs are now off. At the controller, clear its Alarm or Trouble state by pressing and holding the manual reset button (on the front cover) for 2 seconds. Verify that the controller’s Alarm and Trouble LEDs are now off. Replace all panels.

Troubleshooting

Controller’s Trouble LED is On

1.Check the Trouble LED on each sensor connected to the controller. If a sensor’s Trouble LED is on, de- termine the cause and make the necessary repairs.

2.Check the wiring between the sensor and the control- ler. If wiring is loose or missing, repair or replace as required.

Controller’s Trouble LED is Flashing

1.One or both of the sensors is 100% dirty.

2.Determine which Dirty LED is flashing then clean that sensor assembly as described in the detector cleaning section.

Sensor’s Trouble LED is On

1.Check the sensor’s Dirty LED. If it is flashing, the sensor is dirty and must be cleaned.

2.Check the sensor’s cover. If it is loose or missing, se- cure the cover to the sensor housing.

3.Replace sensor assembly.

Sensor’s Power LED is Off

1.Check the controller’s Power LED. If it is off, de- termine why the controller does not have power and make the necessary repairs.

2.Check the wiring between the sensor and the control- ler. If wiring is loose or missing, repair or replace as required.

Controller’s Power LED is Off

1.Make sure the circuit supplying power to the control- ler is operational. If not, make sure JP2 and JP3 are set correctly on the controller before applying power.

2.Verify that power is applied to the controller’s supply input terminals. If power is not present, replace or re- pair wiring as required.

Remote Test/Reset Station’s Trouble LED Does Not flash When Performing a Dirty Test, But the Controller’s Trouble LED Does

1.Verify that the remote test/station is wired as shown in Fig. 23. Repair or replace loose or missing wiring.

2.Configure the sensor dirty test to activate the control- ler’s supervision relay. See “Changing sensor dirty test operation.”

Sensor’s Trouble LED is On, But the Controller’s Trouble LED is OFF

Remove JP1 on the controller.

PROTECTIVE DEVICES

Compressor Protection

Overcurrent

The compressor has internal linebreak motor protection.

Overtemperature

The compressor has an internal protector to protect it against excessively high discharge gas temperatures.

High Pressure Switch

The system is provided with a high pressure switch mounted on the discharge line. The switch is stem-mounted and brazed into the discharge tube. Trip setting is 630 psig +/- 10 psig (4344 +/- 69 kPa) when hot. Reset is automatic at 505 psig (3482 kPa).

Low Pressure Switch

The system is protected against a loss of charge and low evaporator coil loading condition by a low pressure switch located on the suction line near the compressor. The switch is stem-mounted. Trip setting is 54 psig +/- 5 psig (372 +/- 34 kPa). Reset is automatic at 117 +/- 5 psig (807 +/- 34 kPa).

Evaporator Freeze Protection

The system is protected against evaporator coil frosting and low temperature conditions by a temperature switch mounted on the evaporator coil hairpin. Trip setting is 30_F +/- 5_F (-1_C +/- 3_C). Reset is automatic at 45_F (7_C).

Supply (Indoor) Fan Motor Protection

Disconnect and lockout power when servicing fan motor.

The standard supply fan motor is equipped with internal overcurrent and overtemperature protection. Protection devices reset automatically.

The High Static option supply fan motor is equipped with

a pilot-circuit Thermix combination overtemperature/overcurrent protection device. This device resets automatically. Do not bypass this switch to correct trouble. Determine the cause and correct it.

Condenser Fan Motor Protection

The condenser fan motor is internally protected against overtemperature.

Relief Device

A soft solder joint at the suction service access port provides pressure relief under abnormal temperature and pressure conditions (i.e., fire in building). Protect this joint during brazing operations near this joint.
