There are four (4) user-assignable digital inputs configurable to a number of different
functions (see below), or turned Off. Once a function is chosen, any messages that follow
may be used to set pertinent parameters for operation. Each function may only be chosen
once. Assignable Inputs 1 to 4 are activated by shorting D19 to D22 (respectively) with D23.

Assignable Input 4 is dedicated as the two-speed motor monitor and terminals D22 and
D23 are monitored for a contact closure. Closure of the contact signifies that the motor is
in Speed 2 or High Speed. If the input is open, it signifies that the motor is in Speed 1. This
allows the 469 to determine which settings should be active at any given point in time.

Once the Remote Alarm function is chosen for one of the assignable digital inputs, the

chosen. Multiple sources may be used to trigger a remote alarm by paralleling inputs (see
