14 T10 — REMOTE SP ACE TEMPERA TURE SENSOR — Sensor T10 (part no. HH51BX006) is an accessory sensor that is remotely mounted in the controlled space and used for space temperature reset.
15 Thermostatic Expansion V alves (TXV) — Model 30GTN,R and 30GUN,R 040-1 10 units are available from the factory with conventional TXVs with liquid l ine solenoids. The liquid line solenoid valves are not intended to be a mechani cal shut-off. When s ervice is required, use the liquid line service valve to pump down the system.
16 Electr onic Expansion V alve (EXV) (See Fig. 15) — Standard units are equipped wit h a bottom seal EXV . This device eliminates t he use of the l iquid line solenoid pumpdown at un it shutdown. An O-ring has been added t o bot- tom o f orif ice a ssem bly to com plete a se al in the v alve on s hut- down.

45 Cooli ng Se t Point (4 t o 20 mA) — A field supplied and generated, externally powered 4 to 20 mA signal can be used to provide the leaving fluid te mperature set point. Connect the signal to TB6-3,5 (+, – ). See T able 27 for instructions to enable the function.
46 Demand Limit — Demand Li mit is a feature that allo ws the unit capacity to be limited during periods of peak energy usage. There are 3 types of demand limiting that can be confi g- ured. The first type is through 2-stage switch control, which will reduce the maximum capa city to 2 us er-configurable per- centages.
47 TROUBLESHOO TING Compressor Pr otection Control System (CPCS) Boar d — The compre ssor protection board con- trols the compres sor and compres sor crankcase he ater . The ground current protection is provided by the compres- sor board. The large relay located on the board is used to provide a feedback signal to the Ma in Base Board.
48 2. Make sure that thermi stor leads are connect ed to the proper pin terminals at the J5 connector on EXV board and that thermistor probes are located in proper position in the refrigerant circuit.

55 T ube Plugging — A leaky tube can be plugged until retubing can be done. The number of tubes plugged determines how soon cooler must be retubed. T ubes plugged in the following locations will aff.
56 3. Apply torque in one-third steps until required torque is reached. Load all bolts to each one -third step before pro- ceeding to next one-third step. 4. No less than one hour later , retighten all bolts to requi red torque values. 5. Aft er refrigera nt is restored to system, chec k for refriger- ant leaks with soap solution or Halide devi ce.
