2 DEIE FUNTIS T4000/B series The T4000 series are for general use on combustion air dampers and F000 butterfly valves. The version is used with separate power lines to drive the motor to high fire or low fire position. The B version is used in combination with a relay to allow the motor to drive to high fire when the relay is energized and drive to low fire when the relay is de--energized. There are 2 micro switches for auxiliary use. T4001 series The T4001 series can be used with full featured ignition controllers and 3 wire thermostats. This type of motor has three switches for fixed positions of the motor:, low fire and high fire. There is an additional, single pole double throw switch available, which can for example be used for two stage operation of a burner. Optional: push button to allow independent movement of the motor to adjust the low fire position of the damper during installation. T4001B series This type of motor can be used with full featured ignition controllers, where the ignition controller is providing the burner sequence including the drive to high fire during pre--purge. The motor has three switches for three fixed positions of the motor:, low fire and high fire. There is an additional, single pole double throw switch available, which for example can be used for two stage operation of a burner. The motor can be used with the following ignition controllers: gas/oil: Honeywell: SERIES ontrollers Landis & Gyr:... LFL, LGK and LL. Optional: push button to allow independent movement of the motor to adjust the low fire position of the damper during installation. T4001 series This type of motor can be used with Satronic TG740. The ignition controller is providing the burner sequence including the drive to high fire during pre--purge. The motor has four switches which enables the motor to drive to the following three fixed positions:, low fire and high fire. dditional there is a Single Pole Double Throw (SPDT) switch available, which can for example can be used for two stage operation of a burner. Optional: push button to allow independent movement of the motor to adjust the low fire position of the damper during installation. T4002B series The T4002B series can be used in application, where it is allowed to have pre--purge on low fire. This type provides the pre--purge on low fire during the start up sequence. The motor can be used with the following ignition controllers: oil: Landis & Gyr... LO Brahma... GF2 Satronic... TF32 Optional: push button to allow independent movement of the motor to adjust the low fire position of the damper during installation. T4003 series The T4003 series can be used with standard ignition controllers and provides internally the burner sequence to drive to high fire during pre--purge. fail safe pre--purge timer provides pre--purge during 20 seconds on the high fire position. The motor can be used with the following ignition controllers: gas: Landis & Gyr... LGB21 Brahma... F2 Satronic...

Use adjustment tool inside the cover to adjust the cams. Place the tool in one of the cam grooves to turn the cam in steps of approximately 2 degrees. Factory set zero position ll motors are factory set with zero position corresponding with 4 degrees angle of flat surface on actuator shaft ( see Figure 1. When field re--adjustment of zero position is necessary, rotate cam (clock or counter--clockwise) to zero position and re--adjust arrow on scale manually. Low fire adjustment switch (optional) push button switch, to activate electrically movement of the cam assembly, independent from the flame relay signals, is optional on T4001B, T4001, T4002B and T4003 type of servo motors. Use the push button switch to move the cam assembly forward during (re)adjustment of the low fire position of the damper. When this push button is pressed down, the motor will drive to high fire position. When the push button is released, the motor will drive to low fire position. Depending on type, it is positioned either on left or right side of the front plate. am adjustment for servo motors with left hand rotation cam I/ I & I T4000/B series Rotate the cam counter--clockwise to increase the opening position of the air damper Rotate the cam clockwise to decrease the opening position of the air damper Factory set at 0 degrees, to start air damper in closed position T4001/B/, T4002B & T4003 series cam I Rotate the cam counter--clockwise to increase the high fire position of the air damper Rotate the cam clockwise to decrease the low fire position of the air damper Factory set at 0 degrees, to start the air damper in closed position I/I Rotate cam counter--clockwise to increase the low fire position of air damper Rotate cam clockwise to decrease the low fire position of the air damper Rotate the cam counter--clockwise, to delay the switching of the second stage gas valve Rotate the cam clockwise, to advance the switching of the second stage of the gas valve 6
