Relays:
The "contacts" of the twelve relays are present pairwise at the screw terminals at the side. A label
on the VC-1801 relay module clearly indicates the relationship between the relays and the
terminals.
8.1.6
Front Panel Status LEDs (OK)
The front panel of the VC-1801 relay module has a multi-colored LED that indicates the current
status of the device:
•
Green:
Indicates that the supply voltage (+24 VDC) is connected and that the VC-1801 is in good
working condition.
•
Yellow:
Upon initialization after start-up, the LED turns yellow for a very short time to indicate a
system boot up.
•
Red:
Indicates an improper condition on the VC-1801. The cause is often a communication or
configuration error. If the LED is lit
red
on the VC-1801, the "OK" LED on the VIBROCONTROL
18xx also flashes
red
(System Error).
8.1.7
Configuration of VC-1801 with the Compact Setup Software
First the relay module function must be activated in the Compact Setup software.
•
Under menu:
Edit / Monitor / Outputs / Relay Box 1 / activate the selection box (
).
The LED on the front of the VC-1801 relay module indicates with a
Green
LED when the
VC-18xx and VC-1801 modules are communicating.
To set up an independent VIBROCONTROL 18xx, a list of zero to four relays is displayed,
depending on the number of outputs that were assigned to a relay. As soon as a VC-1801 relay
module has been connected to a VIBROCONTROL 18xx, twelve more relays are added to the list
above.
NOTE!
One vibration parameter alarm can have only one relay associated with this alarm.
An alarm relay can be associated with one or more vibration parameter alarms.
