1.3.1 Connect the Power Cable

The controller supports universal power supply ranging from 87V to 264V, 50~60 Hz.

Ferrites

In order to meet certain electrical noise emission limits and to protect the B520 from external influences, it is necessary to install a ferrite core on each cable connected to the terminal.

Wrapping should be done as close to the enclosure as possible.

1.3.2 Connect the Load Cell

If more than one load cells is installed，all load cells should be connected to the junction box first. The combined signal will be sent to B520. To protect the B520 from external influences, the cable between junction box and B520 should be properly shielded. We advise to use the special shield cables supplied by METTLER-TOLEDO.

In addition, the maximum cable distance must be reviewed. The following table provides recommended maximum cable lengths based on cell type and cable gauge.

5 IN5 Sever-valve in poition -

(10)

COM2 External power supply - Ground +24V External power supply + Positive port 24V

Pin Description

run(auto) /stop(manual)

If the input is High-level (connect to +24V pin), controller starts automatic bagging mode;

If the input is low-level (cut off from +24V pin), controller retun to manual mode after current bagging sequence finished.

Emergency Stop

When this pin is high-level (Connect to +24V), controller starts emergency stop process. All discrete output is disabled.

Bag clamp/

loose

Signal valid in rising edge and clamp/loose action is internal interlocked.

Last bag When this input is in high-level, controller adds this last package into total weight. Controller doesn’t compare this weight with the target value. After the last bag weightment completed, Bagging sequence stops. (valid in feed sequence of Bulk Weighing mode ).

Accept tolerance

When this pin is low-level, and the weight has exceeded the target acceptable tolerance, this input being high-level (connect with +24V) will make the controller ignore out-of-tolerance alarm, and accumulate total weight and continue bagging sequence.

Sever-valve in poition

If the sever-valve is installed, the controller detects whether the valve has been completely closed (connect with +24V pin). If not, the next sequence will not start.

Destitute Material

If this input is level-level, the controller stops after current sequence is done, until the input returns to high-level. (only valid in Bulk Weighing and Hopper Batching mode).

This input can also be used for starting bagging sequence.

Full Material When this input detected, controller sends an output signal, which can be used to stop discharging more material unit this signal return low-level. (valid in Hopper and No-Hopper mode).

This signal can be used for dumping the material after weighing.

Hopper Ready/

bag clamped

Start bagging sequence when this port is connected with +24V pin;

In None-hopper mode, the input signal from this pin means bag has been clamped. The controller will tare the scale and start bagging;

In hopper mode, a signal from this pin means the hopper door is in position.

COM COM1 and COM2 should be connecting to the cathode of the external power 24V supply.

+24V Connect to anode of external 24V power supply. The input signal is valid when the port is shortening with +24 pin.

Bulk weighing has two different modes.

1: if Preset accumulation weight is zero (Preset Acc = 0), B520 is working in Bulk Weigh-in mode. System repeats feeding sequence with preset target, until the Last Bag discrete input signal (IN 3) received. System accumulates the total weights and starts to discharge material.

2: If Preset accumulation weight is not zero(Preset Acc≠ 0), B520 is working in Bulk Weigh-out mode. When material in hopper has added to preset weight, system accumulates current weight into totals, and start discharging.

2.11.3 No-Hopper Weighing

This is a bagging sequence with clamping-bag, discharging and other actions. Controller starts bagging sequence after receiving clamping input signal.

Before a bagging cycle starts, controller does tare operation. And when discharging finished, the tare value is cleared automatically.(The tare times can be set in setup menu)

B520 will check the material bag has been in position, or else, controller will stop to wait for for this input or give a alert.

2.11.4 Weighing Indicator Mode(PLC mode)

In this mode, B520 only works as an weighing indicator. When controller started, no input signal is required. The timing parameter can be set in setup menu. The discharging output means bagging sequence finished.

In this mode, B520 is usually a node of PLC network.

Loss in weigh

Mode

When F2 .1 is selected as 4, system works in Loss-in-weigh mode. In this mode, two extra data-settings are added in recipe-setup page: L_SP and H_SP. The “L_SP” is material-low threshold weight and “H_SP” is material-high threshold weight.

Weighing Process:

1: check Meterial-Low input signal. This is an optional selection which can also be disabled in F2.7. if enabled, B520 will not add material (loss weight), until IN6 is high-level；

2: After receiving a bag-clamp input signal, B520 turns on the clamp-bag output signal and waiting the clamp-in-position input signal. (Bag-clamping function is selectable)

3: B520 checks the material weight in hoppers. If current weight is lower than the L_SP threshold value, the OUT4(DIS) turns on. The OUT4 keeps on until the material weight reaches H_SP threshold.

During this process, the fast, middle and fine feeding outputs signal are all turned off.

4: B520 do taring-scale operation automatically. Scale displays a net zero.

5: starts three-speed feeding sequence.

6: when target reached, the feeding weight is added into total if total functionality is enabled.

7: check the feeding tolerance

8: To compare the bags with preset total. B520 repeats bagging cycle until the preset bagging total is reached. (if preset total is 0, bagging cycle is always repeated )
