625X Inductive Loop Detector

Features

• Supply Power: 24 VAC or 120VAC available VA rating: 1.2VA
• Relay 2 Output: Relay2 Output Control Switch on back panel - SW3 SW2 - OFF + OFF= Pulse on Entering the loop, 125mS ±25mS - ON + OFF= Pulse on Leaving the loop, 125mS ±25 mS - OFF + ON = Second Presence Output ON + ON = Loop Fault Output
• Sensitivity: Six sensitivity settings are available using the 3- position front panel slide switch and switch 1 (SW1) on the back panel. MAX = 0.04% MAX = 0.02%, MED = 0.16% MED = 0.08%, MIN = 0.64% MIN = 0.32%
• Frequency Setting: One of three operating frequency ranges can be selected with the front panel slide switch to eliminate cross talk.
• Reset: The Reset button must be depressed for three seconds for automatic retune. If depressed for less than three seconds, it will show loop faults as described below.
• Loop Fault Indicators: If the 625X sees a loop fault (open loop, shorted loop or greater than a 25%inductance change), the Presence LED flashes at a 16Hz rate. If the fault condition corrects itself, the Presence LED and detector resume normal operation. This historic fault can be displayed by depressing the Reset button. The Presence LED flashes at 16Hz rate to indicate a fault has occurred. When the Reset button is released, the detector resumes normal operation within 3 seconds.the Presence LED and detector resume normal operation. This historic fault can be displayed by depressing the Reset button. The Presence LED flashes at 16Hz rate to indicate a fault has occurred. When the Reset button is released, the detector resumes normal operation within 3 seconds.
• Presence Time: 60 minute standard - Options: 8, 16 minutes, or permanent
• Dimensions: 3"H x 1.5"W x 3.5"L (w/o connector)
• Detector Failure Condition: Two factory set options are available: Failsafe (Standard) when supply or loop fails. Presence output falls into detect state. Relay2 output falls in the quiescent state. Failsecure when supply or loop fails. Presence output falls in the quiescent state. Relay2 output falls in the quiescent state.
• Inductance: 18 to 1800 pH (Tuned automatically)
• Frequency Range: 10 to 97 kHz
• Temperature Range: -40°F to +176°F (-40°C to +80°C)
• Outputs: Presence and Relay2 are changeover relay contacts rated at 250VAC, 5A, 150W/600VA max. Optional: Optically isolated contact, 50VDC 50mA.
• Lightning & Transients Protection: Zener diode protection from over voltage induced on loop and feeder leads. Flashover protection from loop to earth. Protection exceeds NEMA specification.
