TDS limiter type FLB1

TDS limiter type FLB1

TDS limiter type FLB1

Application and function

The TDS limiter FLB1 for continuous control of the boiler water electrical conductivity. The measurement of electrical conductivity is done by a measuring cell consisting of the TDS probe and the chamber wall of protection tube.

The product according to PED directive 97/23/EEC annex VII (Module B+D, category II) has the CE-mark no. 0035 of the notified body.

Applied rules as per TRD, AD2000 and "Wasserstand 100".

Function FLB1

The controller continuously measures, at the electrode rod in the measuring cell, the electrical conductivity of the boiler water which is closely related to the level of TDS.

This measured value is compared with the set point of controller. If it is higher or equal than the set point, the controller relay is de‑energised and will go to alarm to shut down the burner. The indicator lamp "STÖRUNG" (alarm) lights. If the measured value drops below 78 % of set point, the controller relay is energised. The indicator lamp "STÖRUNG" does not longer light.

A performance check can be done by pressing and holding of the button "TEST K" (limit value).

In case of failure of the system, e.g. break of mains supply or short circuit, the controller goes in position of higher or equal value than the set point.

The indicator lamp "UB" shows that the power supply is on.

Technical basic equipment

  • FLB1 is delivered in a plastic plug-in housing for installation in control panels
  • Fixation on standard rail 35 mm according to DIN EN 50022 or directly screwed to chassis plate

High water level limiter SMHC1

High water level limiter SMHC1

High water level limiter SMHC1

Application and function

The SMHC1 is a failsafe high water level limiter for use with the level probe type EL 040 or EL 21-2.

It was developed according to DIN EN 50156-1 and the German rule "Wasserstand 100".

The integrated Self-Monitoring-Control System (SMC) is capable of detecting every failure in the moment of its occurrence what will result in an immediate power down of the safety contact and a subsequent burner cut-off.

The product according to PED directive 97/23/EEC annex VII (Module B+D, category II) has the CE-mark no. 0035 of the notified body.

Applied rules as per TRD, AD2000 and "Wasserstand 100".

 

Function SMHC1

The green LED "UB"  is lit when the SMHC1 is connected to the mains supply and it indicates the general function of the limiter. Two special processes of failure detection are running continuously. The first process, checking the proper behaviour of the output circuit, which is responsible for the safety contacts, is performed every 40 ms. The second process, simulating a low water level, is performed every 120 seconds and additionally indicated by the yellow LED "TEST" being lit.

This main test takes about 0.8 seconds. A successful test is indicated by a short flash of the red LED "STÖRUNG". In the case of an un­suc­cess­ful test the acknowledging flash is missing and the next main test will performed already within the next 30 seconds.

After 30 repetitions of this fast test cycle with unsuccessful results, the safety contacts will be powered down and a burner cut-off will be forced. The SMHC1 has an internal fuse (4 A/T) to protect the relay's contacts.

Under normal conditions, only the green LED "UB" is lit permanently  and the yellow LED "TEST" is lit every 120 se­conds for about 0.8 seconds followed by a short flash of the red LED "STÖRUNG". The safety contact is kept energised to maintain the burner protection circuit and the contact "Indication" is open. If the limiter has either detected a failure or the probe's tip is exposed for more than one second, the LED "STÖRUNG" is lit and the contact "Indication" is closed. After a total adjustable delay of 4, 8, 12, 16 seconds, the relays of the safety contact are deactivated and the burner is cut-off. The time delay is preset on 4 seconds.

A circuit to keep the burner from restart is not implemented in the SMHC1 and shall be installed by the customer.
