Connection of signals from the process control system

The following signals must be prepared in the process control system and connected to the
IoT Box:

Signal

Description

Details

Motor current

Analogue signal: 4 to 20 mA

PCS output signal

Current measurement of the bucket elevator’s

main drive.

Level Switch

Digital signal (on/off): 0 / 24 VDC

PCS output signal

Signal of the

level switch in the elevator’s

boot

which acts as overfill indication.

A “0” means overfill, a “1” means no

overfill.

Speed Switch

Digital signal (on/off): 0 / 24 VDC

PCS output signal

Signal monitoring the turning of the elevator

’s

belt.

Straight run
warning

Digital signal (on/off): 0 / 24 VDC

PCS output signal

A belt bucket elevator typically has 4 drift
switches to monitor the straight running of the
belt on the drive and tension drum.
If one of the signals is

indicating a drift a “0”

shall be send to the IoT box. If there is no drift,
the signal shall be

“1”.

IoT Box warning

Digital signal 0 / 24 VDC

PCS input signal

Signal indicating a failure of the IoT Box
1 = all good
0 = IoT more than 12 hours offline

Machine warning

Digital signal 0 / 24 VDC

PCS input signal

Signal indicating a machine warning from
prediction or anomaly.
1 = all good, 0 = warning
Shall not trigger an interlocking but an
inspection of the elevator.
