The setpoint timer parameters are used to display or manipulate the 256 independent setpoint delay timers.
These parameters are not displayable modes of operation, but can be used in custom transmit tables or
macros to display or change timer values.
S ETPOINT C OUNTDOWN T IMER (P ARAMETER 76)
The setpoint countdown timer parameter represents the number of seconds remaining in the activation or
deactivation delay for a specified setpoint. This parameter stores the delay time as an integer value, thus it
reports only a whole number of seconds. When an activation or deactivation delay starts, 76P begins with
the total delay time value and decrements by one (1) each second. A value of zero (0) indicates no delay in
progress.
Since 76P is stored as an integer, it may be formatted as an integer in custom transmit tables. This allows
you to transmit the delay value using time formats such as hh:mm:ss. This is useful for displaying elapsed
time values such as remaining mix time, etc.
Additional time can be added to the remaining activation or deactivation time delay. For example, the macro
command
76.2P+=60%o
could be used to add an additional 60 seconds of mix time to a mixer controlled by setpoint #2.
S ETPOINT D ELAY T IMER (P ARAMETER 77)
The setpoint delay timer parameter represents the number of seconds remaining in the activation or
deactivation delay for a specified setpoint. This is similar to the countdown timer 76P except that the delay
timer is stored as a floating point value. This means that you cannot specify time formats for 77P in custom
transmit tables. However it does have the advantage of being specified in fractions of a second.
S ETPOINT S TATUS (P ARAMETER 78)
The setpoint status parameter provides access to individual setpoint status. For example, assigning 78.1P
to P303 of the setup mode give easy access to the status of setpoint #1 via the [SELECT] key. This also
give you the opportunity to change setpoint status as described on page 2-41.

The random number parameter will generate and display a true random number. This feature is useful in
quality assurance applications to randomly select items for weight verification.
R ANDOM N UMBER (P ARAMETER 79)
The random number parameter generates a random number between 0.0000000 → 1.0000000 exclusive of
the end points. A random number is produced by copying 79P to another operating parameter (usually a
float type variable) or by copying 79P to the entry buffer:
