Fault Finding Fault Finding
Fault Possible reason Remedy
No lighting up of LEDs Mains fuse defective Replace mains fuse
Lamp “Malfuncion” on Basic turbidity of fluid too high Refer to “Basic turbidity too high” in this table
Glass cylinder highly contaminated Clean or replace glass cylinder
Glass cylinder scratched (solids in condensate) Replace glass cylinder. Install ORG 12/ORG 22
acc. to mounting suggestion Fig. 5
Glow lamp in light emitter defective Replace glow lamp
Cable leading to light emitter defective Check cable
Calibration of zero point Cable leading to light receiver defective Measuring of lamp voltage < 12 V only possible
(0 %) not possible if lamp intact
Glass cylinder highly contaminated Clean or replace glass cylinder
Glass cylinder scratched (solids in condensate) Replace glass cylinder. Install ORG 12/ORG 22
acc. to mounting suggestion Fig. 5
Glass cylinder covered with condensation Check gaskets of terminal boxes and glass cylinder,
O-rings of light emitter and light receiver
Drying cartridge assumed pink colour ? Replace drying cartridge
Extremely eccentric position of glow lamp filament Insert glow lamp with central filament position
Basic turbidity of fluid too high Add indicated value of 100 % calibration to turbidity
standard value
No indication of measured Cable leading to light receiver defective Check cable
value
Basic turbidity too high Presence of gas or steam bubbles (flashing) Throttle outlet (indication must drop)
Basic turbidity specific of fluid To measure basic turbidity: Repeat calibration of 0 %
and 100 % with distilled water
Measured value rises If ingress of foreign matter can be excluded, Operate cleaning device more frequently
continually 1 ppm/day growing contamination of glass cylinder
Glow lamp often defective Heat accumulation in light emitter since fluid Remove drying cartridge and install vent nipple
temperature > 60 °C and drying cartridge mounted
