Rear Panel DIP Switch Selections Relay 1 Extend – switch 1 is for extending the detector output after the vehicle has left the loop. Switch 1 in the OFF position provides no extension. Switch 1 in the ON position provides a 5 second extension once the vehicle leaves the loop. This extension applies to relay 1 only. Delay – switch 2 is for providing a 2 second delay, detector will ignore the vehicle until the vehicle has been present over the loop for 2 seconds. Switch 2 in the OFF position provides no delay. Switch 2 in the ON position provides for the 2-second delay. This delay applies to relay 1 only. Presence Time – switch 3 provides for either a 1 hour presence or permanent presence. Switch 3 in the OFF position provides for 1 hour of presence. Switch 3 in the ON position provides for permanent presence. The above presence settings apply to relay 1 only. (Other options are available). Relay 2 Pulse Length – switch 4 provides for either a 250mS pulse length or a 500mS pulse length. Switch 4 in the OFF position provides a 250mS (standard) pulse length. Switch 4 in the ON position provides a 500mS pulse length. Operating Mode – switch 5 and switch 6 determine the operating mode for Relay 2. The four modes are as follows: Switch 5 and switch 6 OFF provides pulse-on-entry. Switch 5 ON & switch 6 OFF provides pulse-on-leaving. Switch 5 OFF & switch 6 ON provides for presence. Switch 5 and switch 6 ON provides a fault output. Front Panel Selections Sensitivity – controlled by front panel rotary switch. - 0 = Low sensitivity - 9 = High sensitivity Medium sensitivity is used for most applications; this is a setting of 4 or 5. Always use the lowest sensitivity setting that detects the desired vehicles. Frequency – four separate settings controlled by front panel. DIP switches. - 2+1 = High. - 2+0 = Medium High. - 1+0 = Medium Low. - 0+0 = Low. Reset – front panel reset performs a hard reset of the detector.

Relay Output Rating: 7A 277VAC/30VDC. Power: 120 VAC (70mA DC or 1W AC) Inductance Range: 20uH to 1500uH. Temperature Range: -30 F to +180 F. Lead-In Length: up to 2500 ft. with proper lead-in and loop. Mechanical: 1 3/8”w X 3 3/32”h X 3 ½”l. Weight: 8 oz. Supply Voltage – incorrect voltage supplied to the unit will not result in damage, the unit will simply not operate until correct voltage is supplied. No fuses need to be reset. Indicators – front panel indicators include: - Power – Green, solid with correct power supplied. - Relay 1 – Red, solid during detect. - Relay 2 – Red, solid during detect. - Fault – Yellow, solid during current fault, flashing for historical fault. Sensitivity Boost – automatic during detect except in the highest sensitivity setting (9). Factory Options: - Presence lengths of 15, 30, 60 minutes or permanent. - Pulse lengths of 250mS, 500mS, 1, 2 or 4 seconds. - Extend times of 0, 2, 5 or 10 seconds. - Delay times of 0, 1, 2 or 4 seconds. - Relay 1 fail-safe or fail-secure. - Relay 2 fail-safe or fail-secure.
