Specifications

Inductance Range:			18 to 1800 micro henries Automatically Tuned
Frequency Range:			10 to 97 KHz
Temperature Range:			-40°C to +80°C
Outputs:			Presence and Relay2 are change over relay contacts rated at 250VAC, 5A, 150W/600VA max.
Optional:			Optically isolated c ontact 50VDC 50mA
Lightning and Transient Protection:			Zener diode protection from over voltage induced on loop and feeder leads. Flash over protection from loop to earth. Protection exceeds NEMA specification.
Supply Power:			24 VAC or 120VAC available. VA Rating 1.2VA
Relay2 Output:			Relay2 Output Control Switch on back panel

	SW3		SW2
	OFF	+	OFF	= Pulse on Entering the loop, 125 mS +/- 25mS
	ON	+	OFF	= Pulse on Leaving the loop, 125mS +/- 25mS
	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.
	SW1= OFF	SW1 = ON
	MAX = 0.04%	MAX = 0.02%
	MED = 0.16%	MED = 0.08%
	MIN = 0.64%	MIN = 0.32%
Frequency:		One of three operating frequency ranges can be selected with the front panel slide switch to eliminate crosstalk.
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 Indications:		If the 625X sees a loop fault (open loop, shorted loop or greater than a 25% inductance change), the Presence LED will flash at a 16Hz rate. If the fault condition corrects itself, the Presence LED and detector will resume normal operation. This historic fault can be displayed by depressing the Reset button. The Presence LED will flash at 16Hz rate to indicate a fault has occurred. When the Reset button is released, the detector will resume normal operation within three seconds.
Detector Failure Conditions:		Two factory set options are available. 1. Failsafe (Standard) when supply or loop fails. a. Presence output falls into detect state. b. Relay2 output falls in the quiescent state. 2. Failsecure when supply or loop fails. a. Presence output falls in the quiescent state. b. Relay2 output falls in the quiescent state.
Presence Time:		60 Minutes standard. Options: 8, 16 minutes or permanent
Dimensions:		3"H x 1.5"W x 3.5"L excluding connector
Connections:
Pin	Function	Wire Color
1	120 VAC (24 VAC option)	Black

3	Relay2 N.O.	Orange
4	Chassis Ground	Green
5	Presence Relay Common	Yellow
6	Presence Relay N.O.	Blue
7	Loop	Gray
8	Loop	Brown
9	Relay2 Common	Red
10	Presence Relay N.C.	White/Black

Contacts are shown in the "NO VEHICLE PRESENT" condition with power applied and loop connected to the detector.
Operating Instructions:
1. Verify the harness is wired per the connection chart and the input voltage is correct. 2. Set the Relay2 Output Control (switches 3 and 2 on the back panel) to the desired function. 3. Set switch 1 on the back panel to the OFF position and SENS switch to MIN setting. 4. Plug in detector. It will automatically tune. 5. Observe vehicle detection's on the PRESENCE LED. If vehicles are not detected, increase sensitivity until detection occurs. 6. If cross talk with an adjacent loop occurs, use the FREQ. switch to change the operation frequency.
