• The two-colour pyrometer should be installed at 90 ° to the measurement object, if possible.
The angle should not be less than 45 ° from the vertical.
• When measuring with a two-colour pyrometer, the measuring field need not be filled completely
EN
by the measuring object. It is also permissible that the received infrared radiation is weakened
by dust, steam or smoke.
Electrical connection
The pyrometer is supplied with low voltage 24V DC (18 ... 32V DC).
ATTENTION
► Switch to neutral and verify absence of voltage
► Connect the instrument according to the following schematic:

The two-colour pyrometer must be protected against high voltage and strong electro-
magnetic fields. Use a shielded cable. The shield must be connected with the connector
housing.
Use a flyback diode when switching inductive loads.
Installation
1. Select a suitable location for the two-colour pyrometer. The following criteria must be ob-
served:
The pyrometer may only be installed by a skilled, qualified electrician. Do not
connect the instrument while the voltage supply source is turned on. Please
observe international safety regulations at all times.
