voltage and frequency have reached the setting of the Standby Voltage and Frequency Sensors, set the switch to ON. This will eliminate the Engine Warmup Timer from any automatic operating sequence. To place the Engine Warmup Timer back into the system, set the switch to OFF. Transfer On Exercise Switch - If it is desired that the load be transferred to the standby source side during the 7-day exercise cycle, set this switch to ON. If no transfer on exercise is desired, set the switch to OFF. Indicator LED's:- The Warmup, Minimum Run, Return To Utility and Cooldown Timer LED's will turn ON when the respective timers are activated.- The In-Phase Transfer Selected LED turns ON when the In-Phase Transfer Select Switch is set to ON. This indicates that the Automatic Transfer Switch will operate in the In-Phase mode and not the Time Delay Neutral mode.- The TDN Timer LED turns ON when the Time Delay Neutral timer is activated.- The Signal Before Transfer Timer LED turns ON when the Signal Before Transfer timer is activated.- The Transfer To Standby LED will turn ON when the load has been successfully transferred to the standby power source.- The Standby Run Signal LED will turn ON when the generator is running and the In-Phase Monitor circuit board is operational and controlling the generator.Calibrating The In-Phase Monitor Circuit Board
In-Phase Monitor Circuit BoardFor proper operation, the In-Phase Monitor circuit board should be calibrated to the existing STANDBY and UTILITY source voltages. The In-Phase Monitor circuit board should be calibrated when the transfer switch has been installed as part of an operating system. Also, replacement circuit boards should be calibrated after installation.To calibrate the circuit board, two adjustment potentiometers (R102 and R107) are provided in the lower left corner of the circuit board. Always calibrate the circuit board in the following sequence:1. Check that the UTILITY supply voltage is available to the system.2. Start the generator set. Allow it to stabilize and warm up. The Standby Run Signal LED should be ON.3. Place the calibration mode switch in the STDBY position. Observe the four top red LED's on the circuit board (Warmup Timer, Minimum Run Timer, Return to Utility Timer and Cooldown Timer). * If the two upper LED's are flashing, calibration is set too low.* If the two bottom LED's are flashing, calibration is set too high.4. On the circuit board, adjust potentiometer R102 until only the Minimum Run LED and the Return To Utility LED (two center LED's of the top four red LED's) are flashing.5. Place the calibration mode switch to the UTIL position. Observe the four upper LED's on the circuit board.6. Adjust potentiometer R107 until only the Minimum Run LED and Return To Utility LED (two center LED's of the top four red LED's) are flashing.7. Place the calibration mode switch to the OFF position. The In-Phase Monitor circuit board is now calibrated. With the calibration mode switch in the STDBY or UTIL positions, the top four
