4 Sequence of Operation Full Voltage Fire Pump Controllers FTA1000 Introduction The following information is in reference to Wiring Schematic, Publication WS Note: Firetrol schematics are drawn showing the equipment in a de-energized state. Energizing The Controller 1. Close the isolating switch/circuit breaker by moving the handle to the ON position. Note: The unmarked, red, Interlock jumper wire, located between terminals #1 & #10 on the Relay PC board, (TB1), will prevent the MarkII unit from starting the electric motor automatically. This jumper wire should only be removed after the pressure settings have been input, and the system pressurized at, or above the Stop set point. 2. The factory programmed MarkII unit will begin initialization. Upon completion, the display will confirm system pressure, the time, date, and Interlock ON, which is an alarm condition and will cause the yellow alarm LED to flash. Any other existing alarm conditions (low system pressure, phase reversal, phase failure, deluge open), will also be sequentially and continuously displayed at this time, until each is rectified. 3. With the interlock jumper wire still in place, the electric motor can only be started by depressing the START push-button, located on the flange of the controller enclosure, or by engaging the Emergency Run Mechanism. After all alarm conditions have been rectified, and the system pressurized at or above the Stop pressure setting, then the interlock jumper may be removed for the controller s automatic operation ( standby ). With the interlock jumper removed, a drop in system pressure to the MarkII s set Start point, will start the electric motor. 4. The deluge valve contacts are only operational if the factory jumper has been removed and a normally closed deluge valve contact has been placed between terminals 1 and 8 of the Relay PC board, (TB1). The Remote Start is only operational if a normally open, momentarily closed contact is wired to terminals 6 and 7 of the Relay PC board, (TB1). If engaged, the Emergency Run Mechanism will cause the pump motor to run as described in the Emergency Starting and Stopping section. Automatic Start and Stop 1). The controller s pressure transducer initiates the automatic start circuits for the pump motor. When pressure falls at, or below the MarkII Start setting, relay 1CR is energized. 1CR normally open contact closes, allowing voltage to the motor starter circuits (see section Pump Motor Starting Sequence for more information) The minimum run time is a part of the MarkII s Menu, Timer Settings. The minimum run timer s factory setting is 10 minutes. In this mode, minimum run time begins when the pressure falls at or below the Start set point, calling for the pump motor to run. When pressure drops, this signals the MarkII to output via the Relay PC board, directly to the 1CR relay coil. The relay s normally open contact closes, allowing line voltage to the coil of the 1M contactor. The contactor s 3 normally open contacts close, allowing 3 phase line voltage to the electric motor, and the motor runs. Simultaneously, the minimum run function of the MarkII is activated, maintaining voltage on the 1CR relay coil, and keeping the motor running until the 10 minutes expire. At this time, with pressure restored at or above the Stop set point, 1CR relay coil will de-energize, re-opening its normally open contact, de-energizing the 1M contactor coil. It s 3 normally open contacts will reopen, causing the motor to de-energize and stop. If pressure is restored at, or above the Stop set point of the MarkII, and even if minimum run time has not yet expired, the manual STOP push button located on the flange of the controller can be depressed to manually stop the engine. This also resets the minimum run time function of the MarkII. Manual Start and Stop The pump motor may be manually started by using either the START push-button mounted on the flange of the enclosure or by using a normally open, momentarily closed, remote start push-button connected to terminals 6 and 7. When the START push-button is depressed, or a remote start signal is seen through terminals 6 & 7, the MarkII will output through the relay pc board to 1CR relay coil and the pump motor will be energized and run as described in section Automatic Start & Stop. The MarkII s minimum run time feature will not be activated. The pump motor will continue to run until the STOP push-button is depressed. When the STOP push-button is depressed, 1CR relay coil is de-energized, interrupting the voltage to the 1M contactor coil, which causes the motor to stop. Deluge Valve Operation To operate the controller utilizing a deluge valve, the wire jumper between terminals 1 and 8 must be removed and a normally closed, open to run deluge valve contact wired in its place.

5 When the deluge valve contact opens, relay 1CR is energized, closings it s normally open contact to the 1M contactor coil, and the motor runs. When the deluge valve contact closes, relay 1CR is de-energized, re-opening it s normally open contact, deenergizing the 1M contactor, and the motor stops. Shutdown Interlock Operation The shutdown interlock, if used, is a normally open, closed to interlock contact wired to terminals 1 and 10. When the interlock contact is closed, relay 1CR cannot be energized by inputs to the MarkII from the pressure transducer, or the deluge valve. The controller may be started manually by depressing the manual START push button. See the specific starting operation for more details. Pump Motor Starting Sequence Whenever relay 1CR is energized, it s normally open contact closes, allowing voltage to the coil of the motor starting contactor. During full voltage starting the following sequence occurs. 1CR normally open contact closes, energizing contactor 1M. 1M connects motor terminals T1, T2, and T3 to the power source. This starts the motor in the full voltage configuration, in which the pump motor draws 100% of its normal inrush current and supplies 100% of its normal starting torque. Emergency Starting and Stopping The controller is equipped with an emergency run mechanism for use in the event of a coil burnout or other electrical problem which would prevent normal starting of the pump motor. The mechanism attempts to both electrically and mechanically start the pump motor. When the emergency run mechanism is utilized, a e-run contact is closed, energizing 1M coil. This, in effect, attempts to electrically start the pump motor. The emergency run mechanism also manually closes the 1M contactor, starting the motor. This will run the motor as long as the main three phase power is available. If the pump motor is running via the emergency run mechanism, DO NOT release the mechanism to stop the motor. Place the isolating switch/circuit breaker handle in the off position, then release the emergency run mechanism. Releasing the mechanism while the motor is running could result in damage to the motor or the motor contactor. Note: The emergency run mechanism is not intended for, nor should it be used as a testing device. Its sole purpose is to attempt to start the pump motor in the event of a failure. SQ ( )
