3.1 General notes on installation

DANGER!

For devices used in hazardous areas, additional safety notes apply; please refer to the Ex documentation.

DANGER!

All work on the electrical connections may only be carried out with the power disconnected.

DANGER!

Observe the national regulations for electrical installations!

WARNING!

During installation of the device make sure that you use ESD (electronic discharge) protection equippment.

WARNING!

Observe without fail the local occupational health and safety regulations. Any work done on the electrical components of the measuring device may only be carried out by properly trained specialists.

INSTALLATION 3

INFORMATION!

Inspect the cartons carefully for damages or signs of rough handling. Report damage to the carrier and to the local office of the manufacturer.

INFORMATION!

Do a check of the packing list to make sure that you have all the elements given in the order.

INFORMATION!

Look at the device nameplate to ensure that the device is delivered according to your order.

3.2 Storage and transport

CAUTION!

Do not store the sensor tip dry. This will shorten lifetime considerably. Always store the pH sensor tip wet in a 3 molar KCl solution when not in use. Saltless water must be avoided since this would leak the KCl ions. The original packing in which the sensor tip was delivered contains a plastic tube with KCl solution and therefore is suitable for storage and transport.

• Since the pH sensor is made out of glass it is very fragile. Avoid shocks of any kind.

• Do not touch or scratch the membrane glass.

• Store the sensor in its original packaging in a dry, dust-free location. Keep it away from dirt. If

necessary, clean it as described on page 24.

3 INSTALLATION

3.3 Installation procedure

WARNING!

During installation of the device make sure that you use ESD (electronic discharge) protection equippment.

Because a new pH sensor needs to be calibrated before it is installed into its final measuring location, it is important to follow the installation order:

1 Unpack the sensor. 2 Connect the sensor to the junction box or directly to the process control system. 3 Calibrate the sensor. 4 Install the sensor into its final measuring location.

The required steps are explained in the following sections.

3.4 Pre-installation requirements

SMARTSENS PH 1590

CAUTION!

•

Never touch or scratch the membrane glass of the sensor.

•

Store the sensor in its original packaging in a dry, dust-free location. Keep it away from dirt. If necessary, clean it as described on page 24

Figure 3-1: Handling the sensor

Unpacking the sensor

• Gently pull the protection cap from the sensor 1.

• Lay the sensor on a soft mat/tissue 2.

• Keep the protection cap in the original packaging 3.

Moisture inside the sensor connector must be avoided! Moisture may cause a shortcut and deliver erratic readings! If moisture has entered the connector dry it with air (e.g. hair blower).

Figure 3-2: Connecting the cable to the sensor

Connecting the cable to the sensor

• Ensure that both cable and sensor connector are absolutely dry 1.

• Screw the cable connector 2 on the sensor and tighten it by hand.
