EN PISA-B-812-B4 Installation Manual
Product Description
The PISA-B-812-B4 is a DIN-rail mountable eight channel protection module with integrated electronic
fuses for 24V systems.
Intended Use
This device is designed for installation in an enclosure and is intended for commercial use, such as in
industrial control, process control, monitoring and measurement equipment or the like.
Do not use this device in equipment, where malfunctioning may cause severe personal injury or
threaten human life without additional appropriate safety devices, that are suited for the end-
application.
If this device is used in a manner outside of its specification, the protection provided by the device may
be impaired.
Installation Instructions
Install the device in an enclosure providing protection against electrical, mechanical and fire hazards.
Install the device onto a DIN-rail according to EN 60715 with the input terminals on top of the unit.
Up to eight devices can be connected via two bus bars, where only the first device is connected to the
power supply. The bus bars must be long enough to make a connection to all contacts of the devices.
Use an appropriately sized 24V power supply, which can deliver the peak current required to trip the
load channels. If peak currents are too low, the supply voltage for the protection module can no longer
be maintained, which results in a malfunctioning of the protection module.
Make sure that the wiring is correct by following all local and national codes. Use appropriate copper
cables that are designed for a minimum operating temperature of 60°C for ambient temperatures up to
+45°C, 75°C for ambient temperatures up to +60°C and 90°C for ambient temperatures up to +70°C.
Ensure that all strands of a stranded wire enter the terminal connection.
The device is designed for pollution degree 2 areas in controlled environments. No condensation or
frost is allowed.
The enclosure of the device provides a degree of ingress protection of IP20. The housing does not
provide protection against spilled liquids.
The isolation of the devices is designed to withstand impulse voltages up to 1.5kV according to IEC
60664-1.
The input can be powered from a regulated power supply or a similar DC source.
The input must be powered from a PELV or SELV source or an “Isolated Secondary Circuit” in order to
maintain a SELV or PELV output.
Check for correct input polarity. The device will not operate when the voltage is reversed.
A disconnecting means shall be provided for the input of the device.
The device is designed as “Class of Protection III” equipment according to IEC 61140.
The device is designed for convection cooling and does not require an external fan. Do not obstruct
airflow and do not cover ventilation grid!
Keep the following minimum installation clearances: 40mm on top, 20mm on the bottom, 5mm left and
right side. Increase the 5mm to 15mm in case the adjacent device is a heat source. Between multiple
PISA-B modules, no clearance is needed.
The device is designed for altitudes up to 5000m (16 400ft).
The maximum surrounding air temperature is +70°C (+158°F). The operational temperature is the
same as the ambient or surrounding air temperature and is defined 2cm below the device.
The device is designed to operate in areas between 5% and 95% relative humidity.
Functional Description
The output can supply any kind of loads, including inductive and capacitive loads. The maximum size
of capacitive loads is specified in the “Technical Data” table. Larger load capacitors might result in an
unintended turn-off of the channel.
Do not load the individual channels with higher average currents depending on the ambient
temperature, as specified in the derating table of this document.
Do not apply return voltages from the load to the output terminals higher than 30V.
Do not parallel outputs for higher output currents.
Do not connect outputs in a series connection for higher output voltages.
Do not connect batteries for charging purposes to the output of the device.
Output channels can be switched on and off separately by pushing the corresponding control button
for longer than 50ms. A switched off channel is displayed with the uppermost red LED of the LED bar
graph.
If the sum output currents is larger than 40A the unit turns off the output channels one after another
until the sum current is below 40A.
The tripping current can be set individually for all channels.
The tripping characteristic can be set as a common parameter for all channels.
Tripping currents and characteristic setting can be protected against changes with a PIN code. To lock
the settings push the SET and channel control button 1 until the unit shows a moving text “PIN TO
LOCK”. Enter a 4-digit PIN by pushing any combination of channel control buttons 1-8. Push the SET
button to save the PIN, the unit shows a moving text “LOCKED”.
To unlock settings push the SET and channel control button 1, the unit shows a moving text “PIN TO
UNLOCK” and enter the 4-digit PIN you selected and confirm it by pushing the SET button.
The device is equipped with a “Digital Coded Alarm Signal” output (pins 13 and 14), which provides
information about individual channel tripping. The signal is an opto-coupler-type output which is low
ohmic for start bit and for tripped channels. The maximal signal current between pins 13 and 14 is
10mA and the maximal voltage is 35V.
The signal sequence starts with 200ms start bit followed by a 100ms gap and 100ms signal related to
CH1 etc. The whole sequence is periodically repeated every 1900ms.

The LED matrix display shows information about measurement, set parameters and errors and
contains two modes. To switch between the two modes, the measurement mode and the parameter
mode, push the SET button and the channel control button 4.
Measurement Mode
The “%” scale on the left side of the LED Matrix is used in this mode, which is also indicated by the
triangular LED below the LED matrix display. In this mode the actual current values are shown and the
LED matrix display also shows, if a channel has switched off due to a too high current or on purpose.
- One or more green/yellow LEDs are on: These LEDs indicate the actual channel current in percent
of the set value. Peak values are stored in a peak detector and are additionally shown with one
LED for a short period of time.
- Uppermost LED is red: This indicates a switched off channel. To switch the channel back on, the
corresponding channel control button must be pressed for at least 50ms. A further push switches
the channel off again.
- Uppermost LED is single flashing in red (2Hz): This indicates that a channel has switched off due to
too high current. A restart can be done either by a button on the unit or by a control signal.
Therefore, push the corresponding channel control button for longer than 1s or apply a voltage
between 10 and 30Vdc (max. 6mA current consumption) for longer than 1s to the reset input. The
reset input is galvanically isolated from the rest of the device.
- Uppermost LED is double flashing in red: This indicates that a channel has switched off because
the total current of the module exceeds 40A. In such cases, first the overloaded channels are
switched off, then channels 8 to 1 in descending order.
- Display of the settings for tripping currents and tripping characteristic: Push the SET button for
more than 50ms. First the tripping currents are displayed, followed by the tripping characteristic
with the letter “F” or “S”. This function ends automatically after 5s.
Parameter Mode
The “A” scale on the right side of the LED Matrix is used in this mode, which is also indicated by the
triangular LED below the LED matrix display. In this mode the set values for the tripping currents for
each individual channel are displayed and the LED matrix display also shows if a channel has
switched off due to a too high current or on purpose.
- Displaying of the setcurrent: Thegreen LED shows theset current of the individual channel.
- Displaying ofthetripping characteristic: Push the SET button.Theselected characteristic isshown on the
LED matrixfor 2 seconds. Letter F indicates the fast and the letter S the slow acting characteristic. The
setting applies to all output channels.
- Red LEDs:These indicate a switched off or overloaded channel and include the same LED blinking
pattern and push-button behaviour as in the measurement mode. If a channelis setto12A, the LED
below theuppermost LED willdisplay this switched-off information.
Changing of Trip Currents and Trip Characteristic
Factory settings are that all channels are turned on with a 1A setting in a fast tripping characteristic
and in measurement mode. Parameters can be changed in the measuring mode as well as in the
parameter mode. Parameters canbe changed regardless ofwhether a channel is switched off or not.
- Changing the current settings: Press and hold the SET button for at least 1s. The triangular green
"A" LED starts flashing. After that, shortly tap the channel control button multiple times to adjust the
current step by step. When the desired setting is found, press the SET buttons for more than 50ms
to save the setting. This mode ends automatically 10seconds after no morebuttons arepushed. In case
the settings are not saved by pressingthe SET button, changesof tripping currents are not stored.
- Changing of the tripping characteristic (slow or fast): To change the characteristic for allchannels push the
SET and thechannelcontrolbutton 3at thesame time. The selectedcharacteristic is shown on the LED
matrix for 2 seconds and stored automatically. Letter “F” indicates thefastand“S” the slow acting
characteristic.
