1.1 How to use this manual
This manual has been designed for electrically skilled persons
working in electrical engineering and electronics!
To make it easier for you to understand and revisit certain sections of text and
instructions in the manual, we have used symbols to identify important instructions and information. Examples of how such symbols are used appear
below:
The warning symbol indicates a potential dangerous
situation that may result in bodily injury and/or damage
to property.
Observe the associated safety instructions.
Information intended to assist the user to make optimum
use of the product are marked with the Info symbol.
1.2 Intended use
The AC/DC sensitive residual current monitor RCMA421H with its measuring
current transformer WN-35BS is used to monitor earthed and resistiveearthed systems (TN and TT systems) in which DC and AC fault currents may
occur. These systems involve loads with six-pulse bridge rectifiers or halfwave rectifiers with smoothing, e.g. converters and chargers.
In the event of a rated residual current I

2. Safety instructions
2.1 General safety instructions
In addition to these operating instructions, the "Important safety instructions
for Bender products“, which are also included in the scope of supply, are an integral part of the device documentation.
2.2 Work activities on electrical installations
Only skilled persons are permitted to carry out the work necessary to
install, commission and run a device or system.
Compliance with applicable regulations governing work on electrical
installations, and with the regulations derived from and associated
with them, is mandatory. EN 50110 is of particular importance in this
regard.
Failure to carry out work on electrical installations properly and correctly can put life and limb at risk!
If the device is being used in a location outside the Federal Republic of
Germany, the applicable local standards and regulations must be complied with. European standard EN 50110 can be used as a guide.

2.3 Device-specific safety information
According to UL943 every residual current monitor and
the associated measuring current transformer is to be
tested in pairs. The relevant serial number for the transformer is imprinted on the enclosure of the RCMA421H.
The residual current monitor and the measuring current
transformer assigned to it may only be used or interchanged in pairs.

3.2 Description of function
The RCMA421H runs a device test when the power supply voltage is connected. During the start-up phase, the TRP LED lights up, the alarm LED ERR flashes
and the alarm relay switches to the alarm setting.
Once the device test has been completed successfully, the ERR alarm LED will
stop flashing, the TPD LED will go out and the alarm relay will return to the
normal setting.

Page 10
Function
The device will check the circuit for the presence of residual currents even during the self test.
An external measuring current transformer (e.g. WN-35BS) is used for residual
current measurement. The actual measured value is indicated on the LCD. If
the rated residual operating current of 6 mA is exceeded, the alarm relay K2
will change to the alarm state and the TRP alarm LED will light up.
Once the alarm relay has switched, the residual current must fall to less than
the rated residual operating current.
If it does not, error code E.04 will appear on the display and the ERR alarm LED
will flash. This means that the connected contactor has not shut down the
faulty circuit.
If the residual current falls below the release value, the error will continue to
be signalled due to the permanently activated fault memory. The alarm relay
K2 will not switch back to the initial state and the TRP alarm LED will not go
out until the reset button R is pressed or the power supply voltage is interrupted.
Parameters are assigned to the device via the LCD and the control buttons on
the front panel; this function can be password-protected.
3.2.1 Transformer monitoring
The connections to the measuring current transformer are checked periodically every 10 s for short and open circuits. In the event of an error, the alarm
relay K2 will switch, the red TPD alarm LED will light up and the yellow ERR
alarm LED will flash (error codes E.01 or E.03). Once the error has been eliminated, the alarm LEDs and the alarm relay will remain in the alarm state. Pressing the reset button R or sending a reset command via the RS-485 interface
will switch K2 back to its initial state and the alarm LEDs will go out.
3.2.2 Quick query of the rated residual operating current
When the display is in standard mode, the rated residual operating current IΔn
= 6 m A can be qu erie d by pres sing the U p or Down butt on (< 1.5 s). S witc hing
to menu mode is not necessary. Quick query mode can be exited by pressing
Enter (< 1.5 s).

Function
3.2.3 Self test, automatic
The device runs a self test every 24 h. Any internal malfunctions detected are
shown on the display as error codes. The automatic self test is carried out
without internal fault current. The alarm relay is not switched during the 24-h
test.
3.2.4 Self test, manual
The device runs a self test when the test button is pressed (> 1.5 s). Any internal malfunctions detected are shown on the display as error codes.
Whilst the test button T is pressed, all display elements available for this device are shown. When the button is released, the tES test symbol appears and
the manual self test commences.
During the manual self test, an internal test current of approx. 7 mA is evaluated. Consequently, the TPD alarm LED lights up and the alarm relay switches.
Once the alarm relay has switched, the residual current must fall to less than
the rated residual operating current. If it does not, error code E.04 will appear
on the display to indicate that the connected contactor has not shut down the
load circuit.
If the self test has been successfully and the reset button R is pressed, the
alarm LEDs will go out and the relay will switch to its initial state.
If the self test has not been successfully, the TPD alarm LED will light, the ERR
alarm LED will flash, the alarm relay will switch to the alarm state and an error
code will be displayed.
3.2.5 Malfunction
In the event of an internal malfunction, the TPD alarm LED will light and the
ERR alarm LED will flash. An error code will appear on the display until the fault
is removed. Refer to page 30 for details about error codes.
3.2.6 Password protection (on, OFF)
If password protection has been activated (on), settings can only be made
subject to the correct password being entered (0…999).

6.2 Error codes
If, contrary to expectations, a device error should occur, error codes will appear on the display. Some of these are described below:
Error code Meaning
Connection error: no transformer
E.01
E.02
E.03
E.04
E…
Action:
Check transformer connection for short circuit or open circuit,
from T to T and from k2 to l2.
Connection error: connection system
(after finishing manual self test)
Action:
Check transformer connection for short-circuit or open circuit.
- Check correct connection, from T1 to T2.
Connection error: short-circuit transformer
Action:
Check transformer connection for short-circuit or open circuit.
Error K1/Q1(following powering up the device)
Action:
Check contactor: e.g. contacts sticking, release coil faulty
Error codes > 04:
Action:
Perform a reset. Restore the device to the factory setting.
Should the error persist, contact Bender Service.
After removing the CT mains connector, the error code E.03 / E.04 alternately
appears on the display.
The error code will be erased automatically once the error has been
eliminated.
