• Must be protected against wetness, moisture, splashed water, and condensate.
• Surge category: II.
• Soiling degree: II.

Requirements for Cables and Lines

• Dielectric strength: 30 V to 260 V according to nominal voltage.
• Cable duct clamping range: 4.5 mm – 10 mm external diameter.
• Terminal strips require core cross-sections of 0.08 mm² to 2.5 mm² (single-wire or fine-wire with ferrules).
• For fine-wire cores with plastic collar ferrules, cross-section up to 1.5 mm².
• Single-wire cores: AWG28 – AWG12.

Requirements for Cable Ducts

• Housing recesses are intended for M16 ducts.
• Duct opening should be smooth and rounded.
• Secure bending protection (five times max. cable diameter).
• Duct must include strain relief.
• Material flammability rating: V1 or better.

Assembly

• Disconnect power before assembly or connection/disconnection from power.
• Connect only to the mains voltage specified on the type plate.
• Observe technical data and environmental parameters.
• Lay mains voltage and relay output cables separately.
• Do not operate without partition walls or terminal area covers.
• ESD Safety: Take necessary measures to avoid electrostatic discharge onto components when opening the casing. Ensure you are earthed.
• Power Switch: The device has no power switch; use an external, clearly marked switch.
• Ensure maximum electrical load capacity of switching outputs is not exceeded (total load must not reach 4A).
• Never attempt to repair the device yourself; repairs must be by authorized personnel.
• Cable Ducting: Loosen strain relief, remove blanking plug, insert cable, tighten union nut.

Connecting Water Intake and Discharge

• Water Temperature: Must be between 10 and 40°C. Water exceeding 40°C can cause burns or damage. A cooler is required for temperatures above 40°C.
• Water Pressure: 0.3 to 8 bar. For pressures of 0.3 to 1 bar, the flow governor core may need to be removed. For pressures under 0.3 bar or suction from a tank, a booster pump (e.g., MepuClip) is recommended. For operation exceeding 8 bar, a pressure reducer is required.
• Intake Lines: Recommended under 3m. For longer lines (>3m), configure purge periods > 60s. For cable lengths > 5-10m, external flushing via AUX is recommended.
• Water Intake Connection:
  • Connect directly to the sampling pipe, vertically upwards.
  • Install a manual stop valve.
  • Use opaque plastic pressure hose 6/4 x 1 (max. 5m).
  • Purge intake to remove dirt.
• Water Drain Connection:
  • Use supplied funnel and drain hose (internal diameter 12 mm/14 mm).
  • Lay hose free of back pressure and siphon effect.

Connecting Mains and Devices

• Risk of Injury: Disconnect all power before assembly.
• Use verified cables with sufficient line cross-section.
• Disconnecting Device: Install an appliance switch or circuit breaker (IEC 608947-1, IEC 60947-3) within reach and clearly marked.
• Electromagnetic Fields: Lay connecting cables separately from mains cables and keep them as short as possible. Shield from strong fields; use a mains filter if necessary. Connect the protective conductor.
• Terminal Designations:
  • PE (IN): Mains protective conductor (for 230V and 100-240V).
  • N (U) (IN): Grid, Neutral conductor (U for 24V).
  • L (V) (IN): Grid, Phase (V for 24V).
  • n (OUT): Neutral conductor, secured with 4A.
  • l (OUT): Phase, secured with 4A.
• System Components: Connect to output terminals of relays 1-4. If requiring mains power, connect external switched mains voltage to the root contact of the respective relay. Connect neutral conductor and protective conductor as applicable.
• External Voltage: If applying external voltages to relay contacts, affix a warning label to the device.

Terminal Outputs

• LV1/LV2 (Limit Value Outputs): Floating relay output, max. 240 VAC, 4 A. Terminals for root c, NO, NC.
• AUX (Auxiliaries): Floating relay output, max. 240 VAC, 4 A. Terminals for root c, NO, NC.
• Alarm (Fault Signal Output): Floating relay output, max. 240 VAC, 4 A. Terminals for root c, NO, NC.

Connecting Inputs and Outputs

• CAUTION: Do not expose connections to external voltage. Ensure cores are securely in place. Incorrect connections will damage the device.
• Current Loop (0/4-20 mA): Galvanically isolated (Out +, Out - terminals).
• Ext. Ack. (External Acknowledge): Input for error/alarm reset. Break/closing contact programmable; use isolated contact.
• WM (Water Meter): Input for water meter signal. Common ground for inputs. Use isolated contact or observe meter specifications.
• Stop: Input for external analysis disruption. Common ground for inputs. Use isolated break/closing contacts.

RS232 Interface Terminal Assignment (Sub-D 9 poles)

• 2: RXD (Data reception)
• 3: TXD (Output of measured values/alarms)
• 5: GND (Ground)

Indicator Bottle Connection

• Flawless operation is guaranteed only with Heyl Testomat 2000® indicators.
• Ensure the screw cap with hole and insert are correctly assembled onto the indicator bottle's suction hose.
• Water Intake Opening: Slowly open the manual stop valve. The measuring chamber should fill within two to six seconds. Restrict intake if water sprays from the measuring chamber hose.
• Automatic Venting: Occurs after switching on; indicator lines are vented and the measuring chamber purged until indicator is detected. This process cannot be interrupted. Acknowledge "voltage failure" error after completion.
