IQ 700 Installation Manual
Modes A, B, C, and D can be used in a independent straight setpoint system or as part of either a manual batching or
automatic batching system. When configured for batching, the setpoints are de-energized except when the batch is
in process. When the setpoint cutoff is reached, the setpoints are latched and will not reactivate until the next
batching sequence.
Modes E, F, and G are dependent modes.
A zero band (ZBD) selectable from ±1 to ±50 displayed graduations around 0 is available in all modes except Mode
C or Mode D, for monitoring an empty scale.
The setpoint parameters are defined in
Table 7-2. Setpoint Parameter Definitions
NOTES:
•
Display indication 11.---- is a default condition created during setup changes to other parameters (
Err 1
).
Re-enter to clear.
•
Logic levels on TB-3 are on at 0VDC (current sinking) and off at 5VDC.
•
Front panel LED’s for setpoints 1 and 2 follow logic level outputs.
•
Setpoints track display readings and will therefore be affected by Gross/Net and Auto Tare operations.
•
In batching modes (
BAT1
and
BAT2
) the setpoint outputs are latched.
•
Internal jumpers S4 and S5 must be in 2-3 position to enable the front panel start switch (S21).
Table 7-3 lists setpoint selections, subparameter information, and their explanation.
