Setpoints
16.1
Introduction
The C500 series has 8 setpoints.
The status of the setpoints is shown on the display (see Section 3.2). An optional output driver module can be
fitted to allow the setpoints to drive external devices. The lamps then show the status of the output drivers.
Each of the setpoints provides a comparator function that can be modified in the digital setup for switching
direction, hysteresis, logic, etc. These settings are all that are required to configure normal level or limit
operation. Free-flight (free-fall) functions can be enabled to configure the C500 series for weight-batching
applications.
Weight target and inflight settings can be pre-set in the digital setup. This method is used where the settings
are changed infrequently, and are to be as tamper-proof as possible. Optionally, weight target and inflight
settings can be set from the front panel keys. This allows settings to be changed much more readily by the
operator.

Connection
Refer to the module datasheet for physical connection details.

General Settings
Settings in the general (GEN) submenu apply to all setpoints.
JOG.ON: If the timing has been set to PULSE this sets the on duration of each pulse.
JOG.OFF: If the timing has been set to PULSE this sets the off time between each pulse.
JOG.SET: If the timing has been set to PULSE this sets the number of pulses to be output each time
the setpoint is triggered before waiting for no motion.
MAX.SET: If the timing has been set to PULSE this sets the maximum number of jog sets to be output
each time the setpoint is triggered. A setting of 0 means no limit.
FEEDER: Controls the behaviour of multiple weigh-in and weigh-out setpoints.
– SINGLE allows only one weigh-in or weigh-out setpoint to be active at a time. Preference is given
to lower numbered setpoints in single mode.
– MULT. allows multiple weigh-in and weigh-out setpoints to be active at the same time.
DLY.CHK: If enabled this starts a delay after a weigh-in or weight-out setpoint has been triggered.
During the delay the weight value will not be checked for weigh-in and weigh-out setpoints.
16.4
Common Settings
There are a number of settings that are common to all setpoint types. These are as follows:
LOGIC: This setting determines whether the output is normally on or normally off.
– Logic HIGH means the output follows the activity of the setpoint and is on when the setpoint
conditions are met.
– Logic LOW reverses the operation of the output.
For example: Consider a Center-of-Zero status setpoint. This type of setpoint is active when the
Centre-of-Zero annunciator is lit. With logic HIGH an output would turn on whenever the Centre-
of-Zero annunciator was lit. With logic LOW the output would turn off when the Centre-of-Zero
annunciator is lit and remain on otherwise.
