SECTION 6: Mechanical installation of the sensor
6-1 Safety notes
Assembly, electrical connection and maintenance must only be carried out by instructed, trained and authorized specialist personnel in accordance with applicable regulations, after de-energizing the power supply and with the machine switched off. Conversions and changes and tampering in the interior of the sensor, the data interface and the alignment tool are forbidden. The ambient conditions at the assembly location must conform to the technical data (see SECTION 3: Specification).
6-2 Sensor assembly
For installation the following points should be considered: · · · · · · · The sensor is protected as far as possible against vibration and shock. The sensor is protected as far as possible against extraneous incident light. The sensor is protected as far as possible against damage and soiling. The sensor is installed in a way so that the electrical connection is possible. The sensor is installed in a way so that the operation of the push buttons is possible. The display is visible.
6-2-1 Sensor's assembly direction
As far as possible, the sensor's optical surface should be aligned parallel to the surface of the retro-reflector.
If the detection object has a glossy, reflecting surface, the object should be tilted by 5° . . . 10° in relation to the surface of the light beam of the sensor.
5° . . . 10°
detection object 90°
6-1 Safety notes
If there is a reflecting surface in parallel with the sensor's optical axis, this might lead to unstable switching states. Therefore, reflecting objects within the sensor's optical axis should be avoided. If this should not be possible, the reflecting surface should not be parallel to the sensor's optical axis, but should be rotated by about 10°. Mirror-like objects can cause malfunction inside and outside the sensing range. Avoid mirror-like objects in or close to the optical axis.
6-2-2 Assembly via assembly holes
1. Professionally produce securing holes/threaded holes corresponding to the six possible assembly holes of the sensor (see Section 3-3 Dimensions). Roughly align the sensor to the possible position of the measured object. Tighten the securing screws.
6-2-3 Assembly by universal mounting bracket E39-EL1
1. Drill and tap the necessary securing holes / threaded holes according to the required pattern of the universal mounting bracket (see 3-4 Dimensions). Using the included securing material, professionally fit the sensor on the mounting bracket. With suitable securing material, professionally fit the mounting bracket on the body of the machine. Roughly align the sensor to the possible position of the measured object. Tighten the securing screws.
6-2-4 Assembly with adapter bracket E39-EL2 and bracket E39-EL1
Applying the adapter bracket E39-EL2 the universal mounting bracket E39-EL1 can be used as an adapter plate to mount the E3NT to existing holes. [. . . ] Digital display: The current received light intensity is depicted in the bar chart. The flashing display " ---- " appears in the event of a short-circuit at the outputs. The sensor continues normal functioning once the short-circuit at the outputs has been remedied.
