Fig. 1: Connection options of a WIC1 with a DiggiMEC and a PC.
The WIC1 can be (optionally) connected to the interface device DiggiMEC, which adds
an LCD display, keys and one or three 󰊠ag indicators. Each 󰊠ag indicator is mechanically
related to a bistable output relay.
The DiggiMEC can be connected to a Windows PC, so that the parameter setting and
evaluation software Smart view can be used to con󰊟gure the WIC1 and to retrieve
measurement values and fault data from it. Moreover, the WIC1 can trigger the 󰊠ag
indicators / output relays.

2 DiggiMEC – Nano HMI with Flag Indicators and Output Relays

CAUTION!
Use an Ethernet cable CAT 3 (or better) with shielding for the connection between WIC1
and DiggiMEC. Crossover cables must not be used!
Make sure that the connection cable between WIC1 and DiggiMEC is mounted according
to all regulations! Respect the manufacturer's spci󰊟cations about permissible bending
radii, and prevent defects by appropriate means such as cable conduits, e. g. if the cable
needs to be bent around sharp corners.
A defective cable might impair the internal voltage of the WIC1 and DiggiMEC, and this
might a󰊞ect the capability of the device to operate a trip coil and outputs.
NOTICE!
The DiggiMEC is always usable only with a connected WIC1 (independent of whether
there is any supply via the USB interface of the DiggiMEC).

WARNING!
A ground connection (functional earth, min. 2.5 mm² [≤ AWG 13], tightening torque
0.5 Nm [4.4 lb⋅in]) must be connected at the “FE” terminal, see diagram ╚═▷ Fig. 6).
In general, all grounding connections must be low-inductance, i. e. as short as possible,
and national standards – if applicable – must be followed.

4.1 DiggiMEC Connectors

RJ45
The DiggiMEC features an RJ45 connector on the rear side. Use a standard network cable
(CAT 3 or better) to connect the DiggiMEC to the DiggiMEC-RJ45-connector of a WIC1.
NOTICE!
Although the communication between DiggiMEC and WIC1 is transferred over a network
cable, note that this is not an Ethernet communication. In fact, a proprietary protocol is
used.
Some WIC1 variants feature another RJ45 connector, that can be used for Ethernet-
based communication, in particular TCP/IP-based SCADA protocols. This Ethernet-RJ45
connector must not be used for a direct connection with a DiggiMEC.
Relay Outputs
The “Outputs” terminals feature:
•For device variants DiggiMEC‑A, one normally-open (Form A) relay contact, that is •mechanically connected with a 󰊠ag indicator.
(Note that this contact is labeled as BO2 within the WIC1 con󰊟guration.)
• For device variants DiggiMEC‑B, one changeover (Form C) and two normally-open• (Form A) relay contacts. Each of these three relay outputs is mechanically connected
with one of the three 󰊠ag indicators.
All relay contacts are bistable and potential-free. They can be triggered by a digital signal
from the WIC1. Since each relay is mechanically connected to a 󰊠ag indicator, switching a
relay means that the corresponding 󰊠ag indicator starts to show its signal, and vice versa.
Further details, in particular about the settings at the WIC1, are here: ╚═▷ “4.2 Flag
Indicator / Output Relays Settings (DiggiMEC)”
WARNING!
Only the trip-coil output “TC+/−” of the WIC1 may be used for tripping a breaker.
The bistable output relays of a DiggiMEC, that is connected to the WIC1, may be used
only for visualization purposes. It is not permitted to use these relay contacts for any
protection-related and/or switching purposes!
If the DiggiMEC relays are used for switching purposes there is the risk of an unreliable
protection of your application!
Remarks with respect to this warning:
•The switching time of the “TC+/−” output is faster than that of a DiggiMEC output •relay. Therefore it is strongly discouraged to use a DiggiMEC output relay for any
protection-related switching purposes.
• It is possible to assign the WIC1 signal »Prot . TripCmd« to a DiggiMEC output• relay. This is absolutely o.k. for visualization purposes. But there is no signaling
back of a DiggiMEC relay status to the WIC1. This has the consequence that the
WIC1 cannot realize any signaling/switching problem if – for instance – there is no
DiggiMEC connected to the WIC1, or if there should be any technical problem with
the DiggiMEC. In such a case the whole protection concept can be void.
14 DiggiMEC DIGGIMEC-1.0-EN-MAN
4 Hardware
4.1 DiggiMEC Connectors

• It is technically possible and permitted to switch the relay contact manually. But if a• breaker should be connected directly to a DiggiMEC output relay, it would be opened
by such a manual switching, and the WIC1 would not be able to detect this. This
makes the whole protection concept unsafe and not permissible.
• The WIC1 Backup Protection cannot switch a DiggiMEC output relay. It only uses the• “TC+/−” output.
15DiggiMECDIGGIMEC-1.0-EN-MAN

4.1 DiggiMEC Connectors

4.2 Flag Indicator / Output Relays Settings (DiggiMEC)
Depending on the ordered type, the DiggiMEC features either one 󰊠ag indicator FI2, or three
󰊠ag indicators FI1, FI2, FI3.
See also ╚═▷ “4.1 DiggiMEC Connectors”.
Each of these 󰊠ag indicators is mechanically coupled with a bistable output relay. At any
time, the DiggiMEC can toggle the state of an FIx. Note that each FIx is always only set with
the rising edge of the assigned signal.
With respect to the DiggiMEC 󰊠ag indicators, there is the following convention: In the state
appearing as a red-colored mark at the DiggiMEC front the 󰊠ag indicator / output relay has
been “set”, and the other state means that the FIx has been “reset”.
WARNING!
A CT-powered DiggiMEC is able to reliably set and reset the 󰊠ag indicators only under the
condition that it is supplied with su󰊡cient electrical energy via the CTs. (Unfortunately
the required electrical energy depends on various aspects, e. g. how many 󰊠ag indicators
shall be switched at the same time, or whether the impulse outputs shall be triggered,
too. Therefore it is impossible to explicitly specify any limit value.)
CAUTION!
It is not possible for the DiggiMEC to check the current state of any FIx. So, if the user
mechanically changes the state of an FIx the new state is not signaled to the DiggiMEC.
In other words: Although it is possible at any time to change the state of an FIx by
hand, this should only be done with great care, being aware of potential consequences,
because this also switches the state of the output relay contacts.
After a reset (via HMI or Digital Input), however, all FIx – regardless whether with
or without latching – (re-)assume their correct states according to the current state
of the assigned signals. (Important: The reset is functional only if the WIC1 settings
have speci󰊟ed which DiggiMEC variant is connected; the related parameter is [Device
planning / WIC1 + DiggiMEC] »DiggiMEC . Mode«.)
RESET
RESET
DiggiMEC_Z07
Fig. 7: Important: Manually toggling the state of a 󰅱ag indicator also switches the contacts of the
respective output relay.
The conditions of a module output or signal of a protective function can be assigned to an
FIx, so that it is both electrically available (via the relay contacts) and visualized (via the 󰊠ag
16 DiggiMEC DIGGIMEC-1.0-EN-MAN

4.2 Flag Indicator / Output Relays Settings (DiggiMEC)

indicator). Since the FIx are bistable the last state remains available even after the WIC1 and
DiggiMEC are no longer supplied (i. e. have been switched o󰊞).
All output relay contacts are potential-free. Each relay can be assigned a signal out of
the »assignment list«.
NOTICE!
Whenever the DiggiMEC is not actively used by a human operator we recommend to
keep the lid closed. (Depending on the local security directives you might also want to
use the sealing option.)
This prevents an unintended re-positioning of the 󰊠ag indicators / output relays.
Furthermore, it reduces the risk of dust or dirt intruding into the mechanics of the 󰊠ag
indicators.

• The connection to the WIC1 has been established.•
• The WIC1 has successfully started all protection functions.•
• The WIC1 has stored su󰊡cient electrical energy to issue a trip impulse.•
See also the chapters “LEDs” and “Troubleshooting” in the WIC1 User Manual.
The other two LEDs are programmable. This means they can be assigned with WIC1-signals,
so that they can inform you about operational states, system data or other WIC1 particulars.
Various signals can be freely allocated to LEDs out of an »assignment list«. (The available
signals can be found in the WIC1 Reference Manual.)

Via the display you can check operational data and edit parameters (of the
connected WIC1).
(6) … (10) Keys
The keys usually react on a short key-press at the moment when the key is released.
Exceptions are the Repeat-functionality of ▲ »Up« und ▼ »Down« and the Special Keys
During Power-on.
After some time without any keystroke the backlight of the display goes o󰊞. Note that
then, while the display backlight is o󰊞, the 󰊟rst keystroke does nothing but illuminating
the display (i. e. the normal key function is ignored).
(6) Navigation Keys
The functions of the keys “◀” (Left), “▶” (Right), “▲” (Up), “▼” (Down) are contextual.
◀ In general, the "Left" key is used to go one step back. You can leave a
submenu. You go back to the previous page of the menu tree.
▶ In general, the "Right" key is used to enter the currently selected
submenu.
▲ In general, the "Up" key is used to scroll upwards. You go to the prior
menu point/one parameter up by scrolling upwards.
▼ In general, the "Down" key is used to scroll downwards. You go to the
next menu point/one parameter down by scrolling downwards.
The ▲ »Up« und ▼ »Down« keys have a Repeat-functionality. If you hold the keys pressed
for some time, the key-stroke gets automatically repeated again and again. This allows for
quickly browsing through a long list.
(7) »Reset« Key
A key-press resets latched signals (including latched LEDs, 󰊠ag indicators and the Fault
Display screen).
See the WIC1 User Manual (chapter “Reset”) for details.

An LED test is always also executed together with the reset: All LEDs 󰊠ash in red color for
(approx.) a second, then 󰊠ash in green color for (approx.) a second.
(8) »★« Key
The “Favorites” key allows for an immediate access to often used menu branches.
For the current Release, there is a 󰊟xed list of entries. (It is planned to allow for individual
choices in a later Release.)

(9) »✕« Key
The “Cancel” key aborts parameter changes.
(10) »↵« Key
The »↵« (»Enter«) key can be used to select new parameter values out of a selection
list or value setting dialog. In any other dialogs the »Enter« key is used to store
prepared parameter changes: By pressing the »Enter« key once the parameter changes are
temporarily stored. These settings are marked by an asterisk symbol (“*”) on the display,
they have not been transferred to the WIC1 yet and are therefore not e󰊞ective yet. If
the »Enter« key is pressed again, those changes are stored de󰊟nitely.
(11) USB Interface (Smart view Connection)
Connection to the PC software Smart view can be done via this USB-C interface.
Moreover, this is a su󰊡cient power supply for DiggiMEC and WIC1, in case the WIC1 is not
supplied via the CTs or any auxiliary power (WIC1‑4 only).
