ZS10 Zero Speed Switch Module

Overview

The Phares Electric Zero Speed Switch Module Model ZS10 is an interface between simple on/off sensors and control circuitry enabling over speed, under speed, and zero speed measurement.

ZS10 Module + Prox Sensor = Zero Speed Switch

The Phares Electric Zero Speed Switch Module Model ZS10 is particularly useful in applications where environmental conditions, such as high temperature, prohibit the use of certain electronics. In these cases, the sensor is installed in the prohibitive area and wired to the Phares ZS10 Zero Speed Switch Module which is located out of the prohibitive area.

For high temperature sensors, see Phares Electric Digital Output Hall Effect Sensors and Gear Tooth Sensors.

Detail

The Phares Electric Model ZS10 Zero Speed Switch System consists of the Phares ZS10 Zero Speed Switch Module, Sensor and Magnetic Sensor Target, all sold separately.

Install the Magnetic Sensor Target at the point of measure. Motion is detected when the rotating Target triggers the Sensor. When motion is either detected or reaches set point, the relay energizes and the relay output changes state. It remains in this state until either under speed or zero speed condition occurs, depending upon the application.

The Magnetic Sensor Target can be a bolt head, gear tooth, key stock, magnet, reflector, or other target depending upon type of Sensor used. The Phares ZS10 Zero Speed Switch Module supplies 12 VDC to an external Sensor. The Sensor must be 3 wire, sourcing (PNP) or sinking (NPN) signal. Sensor input signal is configured via two position selector switch located at the top right of the terminal strip.

The Phares ZS10 Zero Speed Switch Module uses frequency input from various types of sensors to determine the presence of motion or the lack thereof. Use the ZS10 for over speed, under speed, and zero speed applications.

Figure 1. Phares ZS10 Zero Speed Switch Module Indicators and Terminal Block.

The Phares ZS10 Zero Speed Switch Module has 3 diagnostic LED’s. These LED’s indicate Power, Pulses from Sensor input signal and Relay status. LED’s are labeled Power, Pulse, and Relay. A trim pot is used for adjusting the set point.
