6.2.3.1 Response of the Electronic Circuit Breaker with Active Current Limitation

Nominal

current

The function is activated when

• an over-current measured at an output is greater than the corresponding

threshold for the set nominal current (Threshold 1).

• the measured over-current is present for more than 0.1 ms.
The activated circuit breaker can respond in one of three ways:

1. An over-current is present that is greater than Threshold 3

2. An over-current is present that is greater than Threshold 1,

but less than Threshold 2

3. An over-current is present that is greater than the nominal current, but less

than Threshold 1

Manual
Version 1.1.0

32 Function Description EPSITRON®
787-1668 Electronic Circuit Breaker

6.2.3.1.1 Response 1: Over-current present that is greater than Threshold 3

If an over-current is present that is greater than Threshold 3, the current will be
limited to a value situated between Threshold 2 and Threshold 3. This limitation is
effective for at least 50 ms and functions as a variable series resistor. The output
voltage is less than the input voltage.

If the over-current does not decrease, the output concerned will be deactivated
within a period of 50 ms … 5 s.

6.2.3.1.2 Response 2: Over-current present that is greater than Threshold 1, but less than Threshold 2

If an over-current is present that is greater than Threshold 1, but less than
Threshold 2, the output will be deactivated after 5 s.

6.2.3.1.3 Response 3: Over-current present that is greater than the nominal current, but less than Threshold 1

If an over-current is present that is greater than the nominal current, but less than
Threshold 1, the output is not deactivated. This over-current is report, however.

6.2.3.2 Selectiv e immediat e d eact ivation

If the output voltage from the power supply unit drops below 20 V, all outputs
with current greater than the set nominal current are deactivated within 16 ms.

6.5 ON Delay for Specific Channels

The outputs are activated in a staggered manner in the order of their channel
numbers as soon as a minimum input voltage is present. Outputs which have been
de-activated manually, or by a reset signal, are skipped in this process.

The time at which the next output in the sequence is activated is based on the
following conditions:

• At least 50 ms must elapse after activation of the previous output.

• The output current of the previously activated output must lie below the

nominal value set for the output.

6.6 Control Input S1

A signal between S1 and 0 V has the effect that

• all channels previously de-activated due to overloading can now be re-

activated.

• specific channels can be activated or de-activated.

6.6.1 Re-activating Tripped Channels

Apply a signal for at least 0.5 seconds. All channels previously de-activated due
to overloading are then re-activated in sequential order, based on the load applied.

6.6.2 Specific Activation and De -ac t ivation of Non-Tripped Output Channels

A coded pulse pattern must be present to activate and de-activate specific output
channels. The encoded pulse pattern can consist of

• 17 bits or

• 89 bits (with Firmware 2.0 and higher),
which must be transmitted as "Manchester code" (based on IEEE 802.3). Here, a

falling clock pulse denotes a logical zero ("0"), and a rising clock pulse a logical
one ("1").

The first bit to be transmitted has the value "0" and serves as the start bit, after
which either 16-bit or 88-bit user data is transmitted.

No separate pulse signal is applied; the electronic circuit breaker obtains the pulse
signal from the pulse pattern that is received. The circuit breaker is then
synchronized automatically and transmits the current status back via signal output
S2.

The table below provides an overview of the functions for the individual data bits:

Depending on the valence of bit 12 (byte 2), either the set nominal currents or the
momentary output currents are transferred in addition to the momentary input
voltage (see Table 22).

Electronic circuit breakers without active current limitation supply only the
momentary input voltage and the set nominal currents. Output currents are not
transferred.

40 Function Description EPSITRON®
787-1668 Electronic Circuit Breaker

Changing of the signal voltage from 15 V … 30 VDC to 0 V … 5 VDC (falling
clock pulse) corresponds to a logical zero ("0").

Changing of the signal voltage from 0 V … 5 VDC to 15 V … 30 VDC (rising
clock pulse) corresponds to a logical one ("1").

The minimum pulse period is 70 ms, the maximum 200 ms.
A jitter of ±5 % or ±5 ms is acceptable, with the higher value applying.
STOP Bit: The STOP bit uses 1.5 pulse cycles. During this time, the PLC may not

transmit any further bit.
Once the pulse pattern has been transmitted, S1 and S2 are returned to Low. A

new pulse pattern cannot be transmitted until after a period of 200 ms.
The coded pulse pattern must be generated in the PLC via an XOR link from an

auxiliary clock pulse and the data bits. This is illustrated by the examples in the
figures below:

6.7 Signal Output S2

The status of the 8 output channels can be queried at signal output S2. This output
channel is short-circuit proof and has a common potential with the power supply
ground.

Use signal output S2 with a PLC!

Connect the supply ground of the electronic circuit breaker with the ground of the
PLC when you use signal output S2 with a PLC!

When a coded sampled signal is transmitted via control input S1, the circuit
breaker is synchronized automatically. The current status of the output channels is
then transmitted via signal output S2.

The table below provides an overview of the 17 data bits at signal output S2. A
distinction is drawn here between the status "on/off" and the error status
"tripped/overcurrent".

Depending on the valence of bit 12 (byte 2), either the set nominal currents or the
momentary output currents are transferred in addition to the momentary input
voltage (see Table 20).

Electronic circuit breakers without active current limitation supply only the
momentary input voltage and the set nominal currents. Output currents are not
transferred.

6.8 Functioning of Communication between Control Input S1 and Signal Output S2

The 787-1668 electronic circuit breaker can be remotely controlled via control
input S1 when it is linked to a higher-order control system. The operating statuses
can also be read out at the same time via signal output S2.

Figure 21: Example of a pulse pattern at control input S1 an d signal output S2.

1. The PLC transmits a coded pulse pattern to control input S1. The coding is

given in the table "Bit allocation for control input S1". In this case, Bit 10
determines whether output channels are to actually be activated or de­activated.

2. The circuit breaker synchronizes itself automatically. The current status of

all output channels is transmitted back simultaneously via signal output S2.
The transmitted data is not sent as Manchester code, but as binary encoded.

3. The PLC should be programmed such that it applies the current status each

time shortly after any edge slope change to avoid any erroneous signaling or
delays.

4. If there is an overload (over-current) at an output, the circuit breaker will

generate a cyclic pulse at signal output S2. This pulse consists of a 500ms
high signal that is transmitted every three seconds. This pulse continues to
be transmitted until the PLC queries the current status.

6.9 Signal Output S3

A group signal can be queried at signal output S3 to determine the status of the
8 channels. In contrast to signal output S2, output S3 delivers a 24 VDC voltage if
no channel has been tripped. This voltage drops to 0 V as soon as at least one
channel has been tripped.

This output is short-circuit proof and can withstand a maximum load of 20 mA. It
also has a common potential with the power supply ground.

Protect the signal output against voltage peaks!

Voltage peaks can occur at signal output S3 when a relay connected to the unit is
de-activated. This can damage or destroy the signal output. We recommend
installing a recovery diode in parallel to the relay to prevent this.
