Transcription

1 Model T6, Panel Mount Tachometer Features Front programmable Field adjustable parameters Programmable Scaling and Decimal Points 4-20ma Output Signal - Internally Powered by the T6 or Externally Powered 0-10 Volt Output Signal AC or DC Universal Input Voltage 3 Parameter Independent Relays - Each Containing One Form C NO/NC Relay Contact 4 Digit LED Display Code Key Access Gasketed Flange Benefits Prevents equipment damage and material spoilage Prompt alert for stalled, over speed or zero speed conditions Easy interface to existing systems. Sensor Input for Either 2 or 3 Wire, PNP or NPN Sensors Moisture Resistant - Built for Wash Down Areas Overview The T6 Tachometer is a panel mount unit which monitors over speed, under speed, zero speed and at-speed conditions, utilizing a 4-digit display, 0-10V and 4-20mA output signals and three independent isolated relay outputs for speed condition status. The T6 Tachometer helps prevent equipment damage and material spoilage via prompt alert for stalled (zero speed) or under speed condition. It is particularly useful for monitoring under speed conditions as this often indicates an unexpected increase in load which may indicate that an unwanted stoppage is about to occur.

2 Detail The T6 Tachometer is an actual tachometer, not a rate meter posing as one. The T6 Tachometer uses frequency input from a variety of sensors to determine the presence of motion or the lack thereof. Speed is measured in RPM and is monitored using the following output options: Visual speed indication via 4-digit LED display. 0-10V and 4-20mA analog scaled output signals. Three Form C relay outputs. The T6 Tachometer has 3 SPDT Relays with independent set points. When motion reaches set point, the relay outputs change state. They remain in this state until either under speed or zero speed condition occurs. The T6 Tachometer features universal sensor input: 24Vdc, NPN or PNP, 2 or 3 wire sensor. Sensor types compatible with the T6 Tachometer: Hall Effect Photoeye Inductive Capacitive Encoder PharesElectronics.com 2

3 Figure 1. T6 Tachometer Front The front of the T6 Tachometer complies with NEMA 4 standards and is designed and built for use in wash down areas. There are four LED s on the face of the T6 Tachometer: R1 Relay 1, when illuminated, Relay 1 is engaged. R2 - Relay 2, when illuminated, Relay 2 is engaged. R3 - Relay 3, when illuminated, Relay 3 is engaged. S Sensor, when illuminated, Sensor is detecting target. There are four keys on the face of the T6 Tachometer located below the 4 digit display: Arrow Up Increase Parameter Value Arrow Down Decrease Parameter Value P Program, press to advance to the next Parameter S Set, press to access Parameter Value PharesElectronics.com 3

7 Sensors Phares Electronics Digital Output Hall Effect Sensors and Geartooth Sensors are simple on/off non-contact switching devices. Digital output signal is clean, fast and switched without bounce an inherent problem with mechanical contact switches. They are magnetically activated switches which detect the motion of an electromagnet, permanent magnet, or ferromagnetic material with an applied magnetic bias. Phares Electronics Hall Effect Sensors and Geartooth Sensors are produced in a variety of sizes. Please refer to our website for part numbers, or contact us for assistance with choosing a sensor for your application.
