ISS 04 can work on boilers with configuration F1 , F2 , F3 and on water strage vessels with configuration F1 and F4 .
Working with Boilers
1- If your need is to get signals at some levels of water and you don’t concern boiler security etc
then Configuration-I suits your need. No matter 1st rod is shorter than 3rd or 4th rod is taller than
2nd or vice versa. Cut the electrode tips at lengths which levels you need signal at. This working
mode is very rarely used with boilers though. (When electrode is mounted as a spare signaler for instance).
2- If your need is to establish a Fill-Control then Configuration-II or Configuration-III must be used.
? At Conf-II Control mode, the electrode tip-1 is always Low level alarm and the 1st relay
contacts must be in the Burner Security Chain. The 2nd and 3rd electrode tips work for pump
control, and the 4th tip works as High level alarm. Relation between rod lengths will be like
“Le1>Le2>Le3>Le4”.
? At Conf-III control mode, the electrode tip-1 and tip-2 work as Low level alarm together and
the 1st and 2nd relay contacts must be in the Burner Security Chain. The 3rd and 4th electrode
tips work as pump control. Relation between rod lengths will be like “Le1=Le2>Le3>Le4”.
Working with Vessels
1- Use the Configuration-I to have a level signaler. Just cut the rods as you plan. There are no
prediction about the length of rods.
2- Use the Configuration-IV to establisn a Descharge-Control. Relation between rod lengths will be
like “Le1>Le2>Le3>Le4”.
