1 Maintenance

WARNING

Process pressure and temperature, contamination, electrical voltage

Risk of serious or fatal injury

►De-energize the device before removing the rear panel.

►Power can be supplied to switching contacts from separate circuits. De-energize these circuits

before working on the terminals.

►If a sensor has to be removed during maintenance work, avoid hazards posed by pressure, temper-

ature and contamination.

NOTICE

Electrostatic discharge (ESD)

Risk of damaging the electronic components

►For your own safety, only use genuine spare parts. With genuine parts, the function, accuracy and

reliability are also ensured after maintenance work.

►Take personal protective measures to avoid ESD.

1.1 Recommended maintenance

Maintenance work has to be carried out at regular intervals to ensure the efficient operation of the

sampler.

The maintenance work comprises:

• Replacing the wear parts

• Cleaning the device

The cleaning intervals depend heavily on:

• The medium

• The ambient conditions of the sampler (dust etc.)

• The programming intervals

For this reason, adapt the cleaning intervals to your specific requirements but always ensure that these

cleaning tasks are performed regularly.

Replacing wear parts

Wear parts are replaced by Endress+Hauser Service at one- and two-year intervals. Please contact your

local sales center in this regard.

Endress+Hauser offers its customers a maintenance contract. With a maintenance contract, you

can increase your level of operational safety and relieve your operating staff of some of their

workload. Ask your Endress+Hauser Service Organization for detailed information on

maintenance contracts.

►Safeguard the sampler against accidental operation while working on the open peristaltic pump.

Open the peristaltic pump as follows:

1. Take the sampler out of service by pausing a program that is currently running.

2. Open the fastening clip (item 3) and push the pump bracket (item 4) upwards.

3. Remove the knurled head screw (item 7) and open the pump head cover (item 5) to the right.

1. Remove the clamp (item 8) and remove the pump tube (item 2) from the pump.

2. Remove any silicone deposits on the roller (item 10) and the flexible pump bracket.

3. Make sure the roller and all the rolls turn smoothly and evenly.

4. Apply some lubricant to the roller.

5. Secure the new pump tube to the pressure sensor with the clamp (item 8).

6. Guide the pump tube around the roller and insert the marking ring into the groove (item 9), see

→å2.

7. Close the pump head cover and screw it tight. Close the pump bracket.

8. Under Menu/Diagnostics/Term information/Pump tube life reset the tube life to zero by

selecting "Reset".

Calibrate the sample volume each time you replace a pump tube. --> See Operating Instructions

BA489C "Calibration".

NOTICE

Incorrect sample volume

►Only reset the tube life counter to zero once you have successfully replaced the pump tube in order

to avoid incorrect dosing of the medium.
