Why GESTRA Controller internal test error occurs?
- AAshley RiveraSep 23, 2025
The internal test error occurs due to an internal error. Replace the equipment.
Why GESTRA Controller internal test error occurs?
The internal test error occurs due to an internal error. Replace the equipment.
What to do if GESTRA Controller shows error E.005?
Error E.005 may appear if the conductivity electrode is defective, leading to a measured value that is too low. In this case, check the conductivity electrode and replace it if necessary. Also, check the electrical connection. Another cause can be a defective conductivity transmitter, resulting in a measuring current that is less than 4 mA. If this is the case, check the conductivity transmitter and replace it if needed. Also, check the electrical connection.
How to fix GESTRA LRR 1-50 error E.001?
Error E.001 indicates that the temperature sensor is defective or the temperature reading is too low. To resolve this, check the resistance thermometer, conductivity electrode LRG 16-9 and replace it if necessary. Also, check the wiring for any short circuits or interruptions.
What to do if the GESTRA LRR 1-50 Controller shows an actual value less than the set point, causing the continuous blowdown valve to open?
If the actual value is less than the set point and the continuous blowdown valve opens, check code switch S4. Ensure the switch is in the ON position.
What to do if GESTRA LRR 1-50 Controller shows a conductivity electrode defective with reading too high?
If the conductivity electrode reading is too high, check the conductivity electrode and replace it if necessary. Also, check the electrical connection and boiler water.
Why GESTRA LRR 1-50 walkthrough application error occurs?
The walkthrough application error occurs due to an internal error. Replace the equipment.
What to do if GESTRA LRR 1-50 shows a faulty conductivity transmitter with measuring current greater than 20 mA?
If the conductivity transmitter measuring current is greater than 20 mA, check the conductivity transmitter and replace it if necessary. Also, check the electrical connection.
What to do if GESTRA LRR 1-50 Controller shows a faulty conductivity transmitter with measuring current less than 4 mA?
If the conductivity transmitter measuring current is less than 4 mA, check the conductivity transmitter and replace it if necessary. Also, check the electrical connection.
What to do if GESTRA Controller shows actual value less than set point and continuous blowdown valve opens?
If the actual value is less than the set point and the continuous blowdown valve opens, check code switch S4. Ensure the switch is in the ON position.
What to do if GESTRA LRR 1-50 Controller shows a walkthrough test error?
If there is an internal error, replace the equipment.
