Data Sheet for Product

Mechanical design
The HRC3.1 room controller comprises a housing base unit (galvanized sheet steel), a
housing cover (galvanized and painted sheet steel) and a printed circuit board with
plug-in terminals along one side. The printed circuit board and the housing cover are
screwed to the base unit. The room controller also has a female connector for an
external operator or monitoring unit.
The connection terminals can be orders as the HCS3.1 terminal kit (see "Ordering").
Display elements
(service LEDs)
The room controller has four LEDs to indicate the status.
The four service LEDs show the operating states for the HRC3.1 room controller. The
service LED states are:
Operating state LED display
Normal operation CTRL LED1: green, flashing
OK LED2: green, flashing at high frequency
FAULT LED3: off
COM LED4: off
Application (task) stopped CRTL LED1: off
OK LED2: green, flashing at high frequency
FAULT LED3: steady red light
COM LED4: off
Operating system loading OK LED2: Continuous on for ca. 3 seconds
COM LED4: Continuous on for ca. 3 seconds
Then: All LEDs are off
Loaded operating system

All 4 LEDs illuminated
• DIL switch:
Externally accessible quadruple DIL switch S6
The DIP switches can be used in the application and, if necessary, described there.
In the standard application, DIL1 should be set to OFF for transponder card access,
or to ON for magnetic card access.
Settings
• Bridge BR200:
This bridge activates the bootstrap loader when power is restored after a power
failure.
The bridge must be connected before switching on the room controller supply
voltage.
• If the management system or communication link fails, local operation is not
affected.
Response in the event
of a fault
• The power supply component for the room controller has two 1A fusible links which
cannot be replaced.
If these fuses are defective, it is probable that the electronic circuitry is faulty and
that the device needs to be repaired in any case.
• External fuses are required for the 24 V electrical consumers.
Disposal
The device includes electrical and electronic components and must not be disposed of
as domestic waste.
Observe all current local regulations.
