Bringing the boiler, feedwater/condensate tank into service (Group 1..3)
As level and conductivity controllers are factory-set on delivery, they all have the same settings and, if
they are not assigned to different groups, they will be in conflict. This would lead to malfunctions.
For this reason, please follow the procedure below:
1.
Bring Group 1 + Group 2 + Group 3 into service one after another in that order,
so, first Group 1 only, e.g. with the limiters.
2.
Correctly install 120-ohm terminating resistors in the bus at the beginning and end of Group 1.
3.
Once Group 1 is functioning, set the units for the feedwater tank as Group 2, then connect the units of
the second group to Group 1.
You can set the groups to which the level and conductivity controllers belong via a 4-pole DIP
switch in each controller. Set the electrode groups using the rotary knob on the front of each
electrode.
4.
Perform the same steps for the third group, the condensate tank.
