Setpoints; Batch And Continuous Setpoints - Rice Lake 520 Installation Manual

Setpoints

The 520 indicator provides eight configurable setpoints for control of both indicator and external equipment
functions. Setpoints are configured to trip based on specified conditions; tripping the setpoint can be used to
request indicator functions (print, tare, accumulate) or to change the state of a digital output controlling external
equipment.
Figure 12-1 shows the general structure of the SETPTS menu. See Section 3.2.7 on page 31 for a detailed
description of the SETPTS menu. The eighteen setpoint kinds are described in Table 12-1 on page 60.
If the checkweigh function is enabled, setpoints will remain configured but will not function until

up to eight separate batch processing steps. A digital output associated with a batch setpoint is on until the
setpoint condition is met, then latched for the remainder of the batch sequence.
To use batch setpoints, you must activate the BATCHNG parameter on the SETPTS menu. This parameter
defines whether a batch sequence is automatic or manual. AUTO sequences repeat continuously, while
MANUAL sequences require a BATSTRT digital input or BATSTART EDP command before restarting. As
shown in Table 12-1 on page 60, GROSSSP, NETSP, and RELSP setpoint kinds can be configured as either batch
or continuous setpoints.
