[. . . ] When the switch or contact is closed, the motor will accelerate to the Main Speed Potentiometer setting. When the switch or contact is opened, the motor will decelerate to the MIN Trimpot setting (factory set to 0 16 Volts DC). If the MIN Trimpot is set to other than 0 Volts DC, the motor will run at that speed when the switch or contact is opened. An open collector (PNP) can be wired in lieu of a switch or contact. Note: The deceleration time can only be made longer than the normal coasting time of the load.

Wire the switch or contact to Terminals "I1" and "I2", as shown in Figure 7. When the switch or contact is closed, the motor will coast to stop. When the switch or contact is opened, the motor will accelerate to the Main Speed Potentiometer setting. An open collector (NPN) can be wired in lieu of a switch or contact. The Inhibit Circuit is never to be used as a Safety Disconnect since it is not fail-safe. Use only the AC line for this purpose.

Note: Jumper J2 must be set to the "T" position for tach-generator operation. The tach-generator input circuit is designed for a 7 Volt or 50 Volt per 1000 RPM DC tachgenerator used with an 1800 RPM motor. Initially set the IR Comp Trimpot fully counterclockwise. Once the tachgenerator is connected, the IR Comp Trimpot may be increased for additional speed stabilization. 6. 9. 1 Seven (7) Volt per 1000 RPM Tach-Generator ­ Connect the tach-generator positive lead (+) to Terminal "T" and the negative lead (-) to Terminal "I2", as shown in Figure 8. 6. 9. 2 Fifty (50) Volt per 1000 RPM Tach-Generator ­ Connect the tach-generator positive lead (+) to Terminal "B" and the negative lead (-) to Terminal "I2", as shown in Figure 9. 6. 9. 3 Other Tach-Generator Voltages ­ The tach-generator input circuit is designed for a 7 Volt or 50 Volt per 1000 RPM DC tach-generator used with an 1800 RPM motor. For a tach-generator other than 7 Volts or 50 Volts per 1000 RPM, or for a motor other than 1800 RPM, an external 1/2 Watt resistor (RT) must be installed. Install RT in series with the 18 FIGURE 8 ­ DC TACH-GENERATOR CONNECTION (7 VOLTS PER 1000 RPM) Terminal "T" T B J2 PWR ON I2 DC Tach-Generator FIGURE 9 ­ DC TACH-GENERATOR CONNECTION (50 VOLTS PER 1000 RPM) Terminal "B" B T J2 G I2 DC Tach-Generator + G 7V 1000 + PWR ON 50V 1000 Terminal "I2" tach-generator. Connect one end of RT to Terminal "T", connect the other end of RT to the tachgenerator positive lead (+), and connect the negative lead (-) of the tach-generator to Terminal "I2". The value of RT () can be calculated using the following formula: RT = (1. 3 X VT X S) - 16000 Where "VT" is the tach-generator voltage (in Volts per 1000 RPM) and "S" is the base speed of the motor (in RPM).
