Reset Input
This contact is used to clear/reset all local module trip and alarm events from the
trip and alarm latches.
If it is desired to use one module’s contact inputs to also “Reset” the other
modules trip and alarm latches, each module’s Boolean Input Manager logic
function can be configured to do so. Each module’s Boolean Input Manager
function can be configured to accept, only its local Reset contact input, or a
specific module’s Reset contact input, or all modules’ Reset contact inputs.
Note—The Reset button on the front of the module is a local module command
only and cannot be connected to nor affect the “ORed” Reset contact input logic
on other modules.
Speed-Fail-Override Input
This is used as part of the Start Logic “Speed Fail Trip” function. When this
function is enabled, closing the Speed-Fail-Override contact overrides the Speed
Fail Trip. This is a level sensitive trigger so the contact must remain closed to
prevent the Speed Fail Trip until speed is greater than the speed fail setpoint.
Refer to the Start Logic section below for additional details.
If it is desired to use one module’s contact inputs to also function as the “Speed
Fail Override Input” for the other modules, the module’s Boolean Input Manager
logic function can be configured to do so. Each module’s Boolean Input Manager
function can be configured to accept, only its local Speed-Fail-Override contact
input, or a specific module’s Speed-Fail-Override contact input, or all modules’
Speed-Fail-Override contact inputs.

Table 3-4. Dedicated Discrete Input Specifications
Configurable Inputs
Each module has 10 configurable analog/discrete inputs. Each input can be
configured as Not Used, Analog Input, or Discrete Input. User defined names can
be associated with each input.
Discrete Input Configuration Example
When configured as a discrete Input, the channel accepts a 0 / 24 Vdc discrete
input. NOTE: <6 Vdc = FALSE, >12 Vdc = TRUE. The Boolean output associated
with the Discrete input can be used in the user configured software.
