Safety
thermoMETER CTL
1. Safety
System operation assumes knowledge of the operating instructions.
1.1 Symbols Used
The following symbols are used in these operating instructions.
Indicates a hazardous situation which, if not avoided, may result in minor or moder-
ate injury.
Indicates a situation that may result in property damage if not avoided.
Indicates a user action.
iIndicates a tip for users.
Measure Indicates hardware or a software button/menu.
1.2 Warnings
Avoid unnecessary laser radiation to be exposed to the human body.
Switch off the sensor for cleaning and maintenance.
Switch off the sensor for system maintenance and repair if the sensor is integrated into a system.
Caution - use of controls or adjustments or performance of procedures other than those specified may cause
harm.
Connect the power supply and the display/output device according to the safety regulations for electrical
equipment.
> Risk of injury
> Damage to or destruction of the sensor and/or controller
Avoid shocks and impacts to the sensor and the controller.
> Damage to or destruction of the sensor and/or controller

Safety
thermoMETER CTL
The supply voltage must not exceed the specified limits.
> Damage to or destruction of the sensor and/or controller
Protect the sensor cable against damage.
> Destruction of the sensor, Failure of the measuring device
Do not kink the sensor cable and bend the sensor cable in tight radius. The minimum bending radius is
14 mm (static). A dynamic movement is not allowed.
> Damage to the sensor cable, failure of the measuring device
No solvent-based cleaning agents may have an effect on the sensor (neither for the optics nor the housing)
> Damage to or destruction of the sensor
Avoid static electricity and keep away from very strong EMF (electromagnetic fields) e.g. arc welders or
induction heaters.
> Damage to or destruction of the sensor
1.3 Notes on CE Marking
The following apply to the thermoMETER CTL:
- EU Directive 2004/108/EU
- EU Directive 2011/65/EU, “RoHS”, category 9
Products which carry the CE mark satisfy the requirements of the EU directives cited and the European
harmonized standards (EN) listed therein. The EU Declaration of conformity is available to the responsible
authorities according to the EU Directive, article 10, at:

1.4 Intended Use
- The thermoMETER CTL is designed for use in industrial and laboratory areas. It is used for non-contact
temperature measurement.
- The system must only be operated within the limits specified in the technical data, see 3.
- The system must be used in such a way that no persons are endangered or machines and other material
goods are damaged in the event of malfunction or total failure of the sensor.
- Take additional precautions for safety and damage prevention in case of for safety-related applications.
1.5 Proper Environment
- Protection class:
Sensor: IP 65 (NEMA 4)
Controller: IP 65 (NEMA 4)
- Ambient temperature:
Sensor 1: -20 ... +85 °C (-4 ... +185 °F), see also Chapter Measurement
Specification, see 3.3
Controller 2: 20 ... +85 °C (-4 ... +185 °F), see also Chapter Measurement
Specification, see 3.3
Avoid abrupt changes of the ambient temperature of both the sensor and the controller.
> Inaccurate measuring values
- Storage temperature:
Sensor: See also Chapter Measurement Specification, see 3.3
Controller: -40 ... +85 °C (-40 ... +185 °F)
- Humidity: 10 ... +95 %, non-condensing
1) The sensor can be used at ambient temperatures up to +85 °C without cooling. For applications, where
the ambient temperature can reach higher values, the usage of the optional water cooled housing, see Chap.
A 1.3, is recommended (ambient temperature up to +175 °C). The sensor should be equipped with the op-
tional high temperature cable (ambient temperature up to +180 °C), see A 1.4
2) With temperatures < 0 °C (+32 °F), display function is not guaranteed any more.

Laser Safety
thermoMETER CTL
2. Laser Safety
The thermoMETER CTL sensors operate with a double laser sight with a wavelength of 635 nm (visible/red),
see 9.4. The sensors fall within laser class 2 (II). The maximum optical power is ≤ 1 mW.
i
Observe the laser protection regulations!
Although the laser output is low, directly looking into the laser beam must be avoided. Close your eyes or
immediately turn away if the laser beam hits the eye. The housing of the optical sensors may only be opened
by the manufacturer, see 15. For repair and service purposes, the sensor must always be sent to the manu-
facturer.
Lasers of class 2 (II) are not subject to notification and a laser protection officer is not required.
The following warning label must be attached to the cover (front side) of the controller housing.
