External Tamp Disable Switch
A SPDT switch may be connected to Terminal Block 1 (TB1) pins 1 and 2 to implement and
external tamp disable switch. When the switch is closed, +24VDC power is applied to the tamp
valve solenoid. When the switch is open, +24VDC power is removed from the tamp valve
solenoid and the Model 4300 enters Idle mode.
To use the switch, the shorting block SB-1 must be cut on the I/O board. Use caution when
cutting the copper trace as to not cut any other traces.
