1.0 INTRODUCTION

The Barber-Colman two setpoint speed switch normally obtains its input signal from a magnetic pickup which is positioned in proximity to the teeth of a gear on a rotating shaft. The pickup generates an AC signal voltage whose frequency is directly proportional to the rate at which the gear teeth pass by the pole piece. The speed switch converts the input signal voltage into a DC signal which is compared to the preset levels (setpoints) and actuate the relays when the input signal frequency exceeds the preset values.

2.0 SPECIFICATIONS

2.1 ELECTRICAL

2.1.1 COMMON ELECTRICAL SPECIFICATIONS FOR DYNZ-60010, DYNZ-60012 AND DYNZ-60013 Ambient Operating Temperature: -40 to +185°F (-

40 to +85°C).

Maximum Operating Current: 0.20 amperes. Input Signal Voltage: 0 7 Vrms minimum into 33 k

ohm load. Trip Setpoint: Adjustable 325 to 10,000 Hz. SW1: Factory set at 1100 Hz. SW2: Factory set at 3600 Hz.

Repeatability: ±5 Hz or ±1%, whichever is greater.

2.1.2 ELECTRICAL SPECIFICATIONS FOR DYNZ60010 Power Input: 8 to 40 Vdc. Voltage Transients: Withstand 200 volts forward and

reverse peaks of 10 milliseconds duration at 5 ohms source input impedance. Withstand 80 volts forward and reverse peaks of 50 milliseconds duration at 50 ohms source input impedance.

Hysteresis:

SW1: Crank dropout, non-latching; nominal 165 Hz SW2: Overspeed, latching; 100% of setpoint. Relay Contact Rating: 10 amperes at 30 Vdc resistive. Overspeed Response Time: With the overspeed set at 4140 Hz and a steady input frequency of 3600 Hz, then switching the input frequency to 5000 Hz must result in the overspeed relay operating in 90 milliseconds or less.

2.1.3 ELECTRICAL SPECIFICATIONS FOR DYNZ60012 Power Input: 59 to 88 Vdc. Voltage Transients: Withstand 200 volts forward and

reverse peaks of 10 milliseconds duration at 50 ohms source input impedance. Withstand 80 volts forward and reverse peaks of 50 milliseconds duration at 50 ohms source input impedance.

Hysteresis:

SW1: Crank dropout, non-latching; nominal 165 Hz SW2: Overspeed, non-latching; 0% of setpoint. Relay Contact Rating: 0.75 amperes at 88 Vdc resistive. Overspeed Response Time: With the overspeed set at 4140 Hz and a steady input frequency of 3600 Hz, then switching the input frequency to 5000 Hz must result in the overspeed relay operating in 75 milliseconds or less.

2.1.4 ELECTRICAL SPECIFICATIONS FOR DYNZ60013 Power Input: 8 to 40 Vdc. Voltage Transients: Withstand 200 volts forward and

reverse peaks of 10 milliseconds duration at 50 ohms source input impedance. Withstand 80 volts forward and reverse peaks of 50 milliseconds duration at 50 ohms source input impedance.

Hysteresis:

SW1: Crank dropout, non-latching; nominal 165 Hz SW2: Overspeed, non-latching; 0% of setpoint.
