The Filter Change Timer Screen is a count down timer that shows the time
remaining on the currently installed glue filter. When the counter gets down to
zero (0), an alarm can be sounded and the filter needs to be changed or
cleaned. Once the filter has been serviced, the timer can be reset for a user
set time of up to 2000 hours.
The D-90 does not have a filter and, therefore, the factory default timer is OFF.

Internal Level
External Level
There are two level-control inputs that can be used with the D-90, an internal
level sensor and an external level sensor. These inputs can also serve as
internal low and high level sensors. The external level sensor is used for pot
fill mode (see Pot Fill Mode – Section 5). The delay for these sensors to
activate can be set in this screen. These inputs can be enabled, and the time
delay set, on the screen shown below. They can be tied into a programmable
output (see “User Inputs and Outputs,” later in this section).
