6.4.4 Multi-function Relay 1 and 2
The Sunny Island 5048 provides you with several options to control internal and
external operations. For this purpose, two multi-function relays are integrated into the
device with which you can assign functions via the #261 menu using the Rly1Op and
Rly2Op parameters (see section 15 "Relay" (Page 115)).
P
roceed as follows when installing the relay connections:
1.
Pierce a hole in the rubber terminal area at the corresponding position.
2.
Starting from the outside, feed the cable with cable end sleeves through the hole.
3.
Insert the wires with the cable end sleeves in the "Relay1" or "Relay2" connection
terminals of the provided 3-pole print terminals and tighten the screws of these
terminals. The pins have the following meaning:
- NC: Normally closed (closed when in standby)
The relays are changeover contacts. They have both a break contact as well as a
NO contact.
The relay functions are listed as NO contact functions, in other words, the contact
is closed if the relay is activated by selecting the function. For the exception "Alm"
(alarm), the relay has a break function. This means that the relay is normally
activated and opens the contact. It is only deactivated when a fault occurs and
then closes the contact (and thus activates a warning light, for example).
You can only assign one function to each relay. In clusters, the relays of the slaves
can also be used. They are set using the master.
