P100-01 Relay Function
Select Function [0-9] (see manual)
Press
Program the assigned relay using P118, relay logic, so that when you connect the
assigned relay to the weigh bin material feed control device, the weigh bin material feed
stops when the On-Line relay is energized.
Activate On-line Calibration.

Auxiliary inputs (refer to
When the On-line Calibration is activated, normal operation continues until the weigh bin
fills to the maximum level, (90% in the example shown). During the filling stage, the
current level is displayed as a percentage.
On-line Calibration -
Wait for LEVEL > MAX
When the maximum limit is reached, the relay assigned to the On-line Calibration function
energizes to stop the weigh bin material feed.
On-line Calibration -
Wait for LEVEL < HIGH
Material continues to be discharged from the weigh bin, and when the level drops to the
High limit (70% in the example) the On-Line totalizer is automatically activated.
On-line Calibration -
Calibration in progress
When the Low limit (30%) is reached, the totalizer is deactivated and the assigned relay is
de-energized, which reopens the material feed to the weigh bin.
