Description of Operation 4--1 Open–Transition (2–position) Automatic Transfer (4ATS,7ATS,7ATB) Load Transfer To Emergency NORMAL FAILED The sequence for load transfer to the emergency source begins automatically when the controller detects a normal source failure or a transfer test signal. Normal Source Failure. The Normal source is considered unacceptable when any one of six voltage, frequency, or phase rotation conditions occur (see page 3–1).
PAGE 22
4--2 Description of Operation Open–Transition (2–position) Automatic Transfer Switches continued Load Retransfer To Normal NORMAL OK Load on Emerg The sequence for load retransfer to the normal source begins automatically when the controller detects a restored normal source or a cancelled transfer test signal. Normal Source Restoration. The Normal source is considered acceptable again when all six voltage, frequency, or phase rotation conditions occur (see page 3–1). Cancel Transfer Test.
PAGE 23
Description of Operation 4--3 Closed–Transition Automatic Transfer (4ACTS, 7ACTS, 7ACTB) The 4ACTS, 7ACTS, and 7ACTB provides load transfer in either closed (make–before–break) or open (break–before–make) transition modes depending upon the condition of the two power sources. Control logic automatically determines whether the load transfer should be open or closed transition.

4--6 Description of Operation Delayed–Transition Automatic Transfer (4ADTS, 7ADTS, 7ADTB) Load Transfer To Emergency NORMAL FAILED The sequence for load transfer to the emergency source begins automatically when the controller detects a normal source failure or a transfer test signal. Normal Source Failure. The Normal source is considered unacceptable when any one of six voltage, frequency, or phase rotation conditions occur (see page 3–1).
PAGE 27
Description of Operation 4--7 Delayed–Transition Automatic Transfer Switches continued Load Retransfer To Normal NORMAL OK Load on Emerg The sequence for load retransfer to the normal source begins automatically when the controller detects a restored normal source or a cancelled transfer test signal.

A---1 Appendix Controller Cover Removal Hazardous voltage capable of causing shock, burns, or death is connected to controller. Deenergize all power before removing cover. NOTICE ATTENTION Observe precautions for handing electrostatic sensitive devices. The Group 5 controller (CP) is used for sensing, timing, and control functions with 4000 & 7000 Series Automatic Transfer Switches.
PAGE 29
Appendix DIP Switch Actuators A---2 The DIP switch in the Group 5 controller is located on the right side through a opening in the base. The following tables show what each actuator does. Transfer Switch Type DIP switch actuators 1 and 2 select the type of transfer switch used with the controller (open–transition, closed–transition, or delayed–transition). See Table A. Table A. Transfer switch type — DIP actuators 1 & 2.
PAGE 30
A---3 Appendix Frequency of Sources Data Input Lock DIP switch actuator 7 selects either 50 or 60 Hz source frequency. See Table C. The Group 5 controller has an external input for a dry contact that, if closed, prevents setting changes from the keypad. DIP switch actuator 10 selects either yes or no for the external input (such as a key switch). Placing DIP switch actuator 10 in the Yes position enables the controller to respond to the external input. See Table F. Table C.
PAGE 31
Appendix Voltage Jumper Blocks To avoid permanently damaging the Group 5 controller, be certain that the voltage setting matches the transfer switch system voltage. A---4 Eight jumper blocks on the Group 5 controller are arranged in one of two patterns for the power supply to meet the requirements of the 16 different voltage inputs (shown in Table B on page A–2). These jumpers are located on the front right side near the ribbon cable. See Figures A–3 and A–4.
