8.4 Menu 1.2 Calibration
Please refer to chapter 7 “Commissioning”, pg. 43.
8.5 Menu 1.3 Limits
1.3.1 Limits 1 / 2
Menu 1.3 is containing limit setting for belt speed, flow rate and belt load.
To all limits an alarm delay can be added.
The limits will switch with undergoing the defined minimum and exceeding
the defined maximum for a time >= defined alarm delay.
Limits will be visualized in the operating menu (s. chapter “8.1.1 Dynamic
status in operating view”, pg 60). Further they can be readout via digital
outputs or RS485.
Dropping below the minimum belt speed is displayed in the status area
of the scale. The specification is made in % of the nominal belt speed
which was specified during commissioning or calculated.
Exceeding the maximum belt speed is displayed in the status area of
the scale. The specification is made in % of the nominal belt speed
which was specified during commissioning or calculated.
Violation of the limits for the belt speed is delayed by the specified time.
The specification is made in ms.
Dropping below the minimum flow rate is displayed in the status area of
the scale. The specification is made in % of the design flow rate.
Exceeding the maximum flow rate is displayed in the status area of the
scale. The specification is made in % of the design flow rate.
Reaching the maximum flow rate is displayed in the status area of the
scale only following expiry of the delay. The specification is made in ms.
Dropping below the minimum belt load is displayed in the status area of
the belt scale. The specification is made in % of the nominal belt load
which was determined during commissioning.
Exceeding the maximum belt load is displayed in the status area of the
belt scale. The specification is made in % of the nominal belt load which
was determined during commissioning.
Violation of the limits for the belt load is delayed by the specified time.
The specification is made in ms.
