Hmi-Dm, Hmi-Tm - Remak VCS Installation And Operating Instructions Manual

HMI-DM, HMI-TM

HMI-DM (HMI-TM) control devices ensure communication
between the VCS control unit and the user. They are intended
for air-handling device control, handling and service. The HMI
control device can be connected to the POL4xx or POL6xx
controllers. During controller operation, a single HMI control
device can be connected or disconnected and alternatively (in
sequence) used to control multiple control units (controllers).
Connection
The HMI-DM controller can be connected using a serial inter-
face (4-wire, twisted pair) with two RJ45 connectors. The
cable length is 1.5 m (the cable is included in the delivery).
When installed on a wall, the HMI-DM controller can be con-
nected using a shielded 8-wire UTP cable with two RJ45
connectors. The maximum distance is up to 50 m.
The HMI-TM controller can be connected to the control unit
using a 4-wire cable (twisted pair) with one RJ45 connector
and one slim connector. The cable length is 2.5 m (the cable
is included in the delivery).
Warning
After connecting the controller to the control unit, it is nec-
essary to route the cable through the PG16 grommet. Thus
degree of protection IP20 is ensured. If a higher level of protec-

Device Description
The controller consists of two separate parts – the face plate
with a display and the rear plate. Dimensions of the HMI-DM
controller are 144x96x26 mm and the integrated LCD display
resolution is 208x96 pixels. The display can show 8 lines. The
HMI-DM controller is equipped with three function buttons,
INFO, FAILURE and ESC, and one scrolling knob. The
scrolling knob and buttons are used to navigate within the
menu and to change the parameters and control values. The
INFO, FAILURE and ESC buttons are equipped with LEDs to
indicate operating states.
The controller can also be delivered in a version for free loca-
tion. The magnets on the rear side of the HMI enable the con-
troller to be attached to metal parts (e.g. the air-handling unit).
For fixed mounting, the controller is equipped with threaded
holes on its rear side to screw it to the mounting plate.
tion of the distribution board cas-
ing is required, the grommet will
have to be resealed. An optional
grommet with an RJ 45 connector
can be used to make it easy to con-
nect (disconnect) the HMI control-
ler (an extra order is required, not
included in the standard delivery).
Then the RJ45 connector must
be connected to the RJ45 socket
on the controller. For the socket
marking, see the figure.
