PCB Jumper Positions

3.9.1.

On/Off Key Disable

There is a jumper, W2, close to the keypad connection that determines if the On/Off key operates or
if the key function is disabled and the IND560x terminal always power up in the "On" condition. In
applications where an operator is not normally present, it is suggested that the jumper be removed
from the two pins so the terminal will return to operation after a power outage. Figure 3-47indicates
the jumper's location and positions.
3.9.2.

2mV/V 3mV/V Jumper

The IND560x Main board has a jumper, W1, which selects either 2 mV/V or 3 mV/V operation of
the analog circuitry when the Analog load cell connection is activated on the main board. This
jumper is not used when the IDNet or SICSpro connection is activated on the IND560x main board.
Figure 3-48 indicates the jumper's location and positions.

When both SW1-1 and SW1-2 are positioned ON and AC power is applied to the terminal,
a Master Reset function will be initiated. This procedure will erase all programming in the
terminal and return all settings back to factory default values. Metrologically significant data
(calibration) is not reset unless SW2-1 is also set to ON during this process. This process
is further described in the IND560x Technical Manual, Chapter 4, Service and
Maintenance.
Figure 3-47: On/Off Key Disable Jumper
When removing the W2 jumper for disabling the On/Off key, reposition it on just one of the pins
as shown at lower right in Figure 3-47. The On/Off jumper settings are described in Table 3-21.
