Remote Key Connections

The 460 and 560 Series indicators accommodate two remote key connections and the 660 Series up to eight different remote key connections. A remote switch may be connected to the main board to provide remote activation of print, tare, or zero functions by invoking a macro. Other functions can be invoked through the macro also.

A two-conductor shielded cable between 28 and 20 AWG is recommended. The input requires a contact closure from a push-button switch, a "dry" relay contact, a photo-eye, and a proximity sensor or other such device.

A closure initiates the operation specified at macro 6 or macro 7 on the 460 and 560 Series or setpoints 131-138 on the 660 Series. A closed switch will conduct 2.2mA.

Caution: Do not apply an external voltage to remote key terminals! Only a contact closure is required to activate the remote key input.

The open circuit voltage across the remote key pins is +5 VDC. A closed switch will conduct about 0.25 mA. Therefore, a low-voltage switch with gold-plated contacts is recommended. A Mercury-wetted switch will also work well. A minimum contact duration of 100 ms is required. Once invoked, the selected remote key operation will not repeat until the contact is released and closed again.

460 Series Remote Key Connection
Connect one wire of the remote key (switch) to position 1 or 2 of J9 on the main board and the other wire of the switch to ground (GND) of J9.

560 Series Remote Key Connection
Connect one wire of the remote key (switch) to positions 1 or 2 of J15 on the main board and the other wire of the switch to ground (GND) of J15.

660 Series Remote Key Connection and Configuration
Connect one wire of the remote key (switch) to position 1-8 of J15 on the main board and the other wire of the switch to ground (GND) of J15.
