System 2 Installation / Programming Manual

My proximity reader works, but doesn’t have the advertised read-

range

Possible Cause:

U Installing the read head in the vicinity of metal will reduce the read-range slightly.

U Do not install the read-head near a Video Display Terminal or computer screen.

U Verify that the voltage out at the read-head is 10.5 - 14 VDC.

I get a “Duped Slave” message on the master System 2 in my network

Possible Cause:

U Two “slave” System 2 boards have been programmed with the same slave number.

I get a “slave down” message on the LCD

Possible Cause:

U The system is only a 2-door unit but has been programmed for network use.

U One of the units hasn’t been programmed for network use or there is a break in the wiring

between the units.

When the main relay activates, the system locks up, loses memory or

resets

Possible Cause:

U When using a DC door lock, a diode must be properly installed across the coil of the lock.

U Check Terminal #1 (earth ground). Make sure a resistance reading between earth ground

and electrical ground is 5 ohms or lower.

U Be sure AC locks are not being used.

When I power the board down and power it back up I lose memory

Possible Cause:

U Check the lithium battery BT1 on the upper right hand corner of the board, it should measure

2.8 to 3.0 VDC.

U Before you power down make sure the jumper is across pins 1,2 on header H4.
