seconds. The duration of the flashing within these 2 seconds depends on the bus load. The
higher the bus load is the longer the duration of the flashing within these two seconds will be.
CONTROL PORT
The CONTROL PORT contains four freely programmable
control inputs, three freely programmable control outputs,
one ready/fault output as well as reference connections for
ground, +5 V and +10 V.
The control inputs IN1 - IN4 are DC inputs, which internally
are connected to ground via pull-down resistors. From
external sources voltages between 0 V and +10 V are
possible. Either switch-mode functions or variable functions
can be programmed for the control input via the IRIS-Net PC
software. Examples of use are: power on/standby switching, preset switching or parameter
control.
The control outputs OUT2 - OUT4 are relay contacts, which are open circuits in off-state (off).
When the output is in on-state (on) the outputs are connected to ground. The outputs are able to
signal internal states and they can directly operate LEDs, indicator lights or relays. The +5 V
reference voltage is able to energize the externally connected elements with up to 200 mA.
Operating states (critical temperature, overstepping or falling below of defined limit values, faults,
etc.) can be relayed to central operation stations or other systems (fire alarm systems, life safety
systems) even without use of a PC via the control outputs. You will find detailed information
regarding configuration of the control ports in the IRIS-Net documentation.
Mains Connector and Power Switch
Please use the enclosed power cable in order to connect
NetMax N8000 to the mains power supply. The N8000 is
compatible with a supply voltage between 100 V AC and
240 V AC. Therefore, a supply voltage switch is not
necessary. Internally, there is a mains fuse which is normally
only blown in case of a fault. The fuse should only be
replaced with an equivalent fuse with identical values for
current, voltage and actuating characteristics by an
authorized service center.
The N8000 can be switched on and off with the power switch on the rear of the device. The ON-
LED on the front panel is immediately illuminated after switch-on. The N8000 boots and initializes
all parameters with those values that had been previously active. The initialization takes some
seconds. As soon as N8000 is ready for operation, the READY-LED is also illuminated.
