inside surfaces. Check belt tension by using a spring-- force tool (such as Browning’s Part Number “Belt Tension Checker” or equivalent tool); tension should be 6-- lbs at a 5/8-- in. deflection when measured at the centerline of the belt span. This point is at the center of the belt when measuring the distance between the motor shaft and the blower shaft. To change fan speed: 1. Shut off unit power supply. 2. Loosen belt by loosening fan motor mounting nuts. (See Fig. 5.) 3.
When replacing the motor, also replace the external-- tooth lock washer (star washer) under the motor mounting base; this is part of the motor grounding system. Ensure the teeth on the lock washer are in contact with the motor’s painted base. Tighten motor mounting bolts to 120 +/-- 12 in-- lbs. Changing fan wheel speed by changing pulleys: The horsepower rating of the belt is primarily dictated by the pitch diameter of the smaller pulley in the drive system (typically the motor pulley in these units).

operation are factory-- provided and mounted. The unit is factory-- configured for immediate smoke detector shutdown operation; additional wiring or modifications to unit terminal board may be necessary to complete the unit and smoke detector configuration to meet project requirements. System inspections without having to disassemble the sensor. The cover attaches to the sensor housing using four captive screws and forms an airtight chamber around the sensing electronics.
For installations using two sensors, the duct smoke detector does not differentiate which sensor signals an alarm or trouble condition. Smoke Detector Locations 50TC Supply Air — The Supply Air smoke detector sensor is located to the left of the unit’s indoor (supply) fan. See Fig. 18. Access is through the fan access panel. There is no sampling tube used at this location. The sampling tube inlet extends through the side plate of the fan housing (into a high pressure area).
6. For units with an economizer, the sampling tube is integrated into the economizer housing but the connection of the flexible tubing to the sampling tube is the same. Highlight B: Smoke detector NC contact set will open on smoke alarm condition, de-- energizing the ORN conductor. Highlight C: 24-- v power signal via ORN lead is removed at Smoke Detector input on LCTB; all unit operations cease immediately.
Sensor and Controller Tests The sensor alarm test checks a sensor’s ability to signal an alarm state. This test requires that you use a field provided SD-- MAG test magnet. OPERATIONAL TEST HAZARD Failure to follow this caution may result in personnel and authority concern. Pressing the controller’s test/reset switch for longer than seven seconds will put the duct detector into the alarm state and activate all automatic alarm responses.
50TC Changing the Dirt Sensor Test 12 By default, sensor dirty test results are indicated by: S The sensor’s Dirty LED flashing. S The controller’s Trouble LED flashing. S The controller’s supervision relay contacts toggle. The operation of a sensor’s dirty test can be changed so that the controller’s supervision relay is not used to indicate test results. When two detectors are connected to a controller, sensor dirty test operation on both sensors must be configured to operate in the same manner.
Table 3 – Detector Indicators Alarm LED Trouble LED Dirty LED Power LED ! DESCRIPTION Resets the sensor when it is in the alarm or trouble state. Activates or tests the sensor when it is in the normal state. Indicates the sensor is in the alarm state. Indicates the sensor is in the trouble state. Indicates the amount of environmental compensation used by the sensor (flashing continuously = 100%) Indicates the sensor is energized.
S If a wiring fault between a sensor and the controller, the controller’s Trouble LED turns on but not the sensor’s. Trouble Alarm 2. Check the wiring between the sensor and the controller. 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 controller is operational. If not, make sure JP2 and JP3 are set correctly on the controller before applying power. 2.

50TC timeclock function in place of the jumper between TR and N. (See Fig. 52.) When the timeclock contacts are closed, the EconoMi$er IV control will be in occupied mode. When the timeclock contacts are open (removing the 24-- v signal from terminal N), the EconoMi$er IV will be in unoccupied mode. Demand Control Ventilation (DCV) When using the EconoMi$er IV for demand controlled ventilation, there are some equipment selection criteria which should be considered.
This procedure is used to prepare the EconoMi$er IV for troubleshooting. No troubleshooting or testing is done by performing the following procedure. NOTE: This procedure requires a 9-- v battery, 1.2 kilo-- ohm resistor, and a 5.6 kilo-- ohm resistor which are not supplied with the EconoMi$er IV. IMPORTANT: Be sure to record the positions of all potentiometers before starting troubleshooting. 1. Disconnect power at TR and TR1. All LEDs should be off. Exhaust fan contacts should be open. 2.
PRE--START--UP 2. Set the Enthalpy potentiometer to A. The Free Cool LED turns on. The actuator should drive to between 20 and 80% open. 3. Remove the 5.6 kilo-- ohm resistor and jumper T to T1. The actuator should drive fully open. 4. Remove the jumper across T and T1. The actuator should drive fully closed. 5. Return EconoMi$er IV settings and wiring to normal after completing troubleshooting.
4. Verify the following conditions: a. Make sure that condenser-- fan blade are correctly positioned in fan orifice. See Condenser-- Fan Adjustment section on page 11 for more details. b. Make sure that air filter(s) is in place. c. Make sure that condensate drain trap is filled with water to ensure proper drainage. d. Make sure that all tools and miscellaneous loose parts have been removed.
Use the Carrier network communication software to start up and configure the PremierLink controller. Refer to Installation Instruction 33CS-- 58SI for full discussion on configuring the PremierLink control system. Changes can be made using the ComfortWORKSr software, ComfortVIEWt software, Network Service Tool, System Pilott device, or Touch Pilott device.
outdoor-- air dampers closed to maintain the proper supply-- air temperature. compressors 1 and 2 will be cycled based on Y1 and Y2 inputs respectively. HEATING, UNITS WITH ECONOMI$ER IV — When the room temperature calls for heat, the heating controls are energized as described in the Heating, Units Without Economizer section. Any time the compressors are running, the PremierLink controller will lock out the compressors if the SAT becomes too low.
50TC Heating may also be energized when an IAQ sensor installed and has overridden the minimum economizer damper position. If the OAT < 55_F and an IAQ sensor is installed and the IAQ minimum position > minimum damper position causing the SAT to decrease below the SPT - 10_F, then the heat stages will be cycled to temper the SAT to maintain a temperature between the SPT and the SPT + 10_F.
The fan will also continue to run as long as compressors are on when transitioning from occupied to unoccupied with the exception of Fire Shutdown mode. If the Fire Shutdown input point is closed or forced in the STATUS01 points display table, the fan will be shutdown immediately regardless of the occupancy state or demand. The PremierLink controller has an optional Supply Fan Status input to provide proof of airflow.
return to normal when the indoor relative humidity drops 3% below the active humidity setpoint. 50TC Economizer — The economizer dampers are used to provide free cooling and indoor air quality if optional CO2 sensor is installed and when the outside conditions are suitable. Temperature control is accomplished by controlling the SAT to a certain level determined by the Economizer PID Loop by calculating a submaster reference (ECONSR) value.
The maximum number of stages available is dependent on the type of heat and the number of stages programmed in the CONFIG and SERVICE configuration tables. Staging will occur as follows for gas electric units, Carrier heat pumps with a defrost board, or cooling units with electric heat: For Heating PID STAGES = 2 HEAT STAGES = 1 (50% capacity) - energize HS1. HEAT STAGES = 2 (100% capacity) - energize HS2.
equal to OCSP and Enthalpy = Low then PURGEMP = 100%. S If the OAT < NTLO then PURGEMP = LTMP (Low Temperature Minimum Position - defaults to 10%) S If the OAT > 65_F or (OAT ≥ NTLO and OAT > OCSP) or Enthalpy = High then PURGEMP = HTMP (High Temperature Minimum Position defaults to 35%). 50TC The LTMP and HTMP are user adjustable values from 0 to 100% in the SETPOINT table.
