11.3 Add-on
parts
11.3.1 Level monitoring
An ultrasonic sensor monitors the lubricant level in the container or the barrel and sends a signal at minimum level.
The ultrasonic sensor sends a signal for barrel exchange as soon as the barrel is empty. The signal evaluation is done by the customer.
Two TEACH modes are available to configure the sensor:
Individual programming of the lower and upper limit values, or
Use of the “Auto-Window” feature to create an acquisition window around the programmed position.
Also observe the technical documentation of the ultrasonic sensor enclosed.
In order to avoid that air is sucked into the lubrication circuit, the device should be switched off at an empty
signal.
11.3.2 Ventilation valve
The ventilation valve in the reservoir cover is used to filter the incoming air during the pressure compensation that is caused by a
varying level. The ventilation filter element has to be checked at regular intervals and renewed if it is visibly polluted.
11.3.3 Grease level dipstick
If the grease level dipstick is pulled out of the reservoir, the lubricant level is displayed at the stick. In order to avoid that dirt enters the
reservoir, the dipstick has to be completely inserted into the bore.
11.3.4 Single-line block (optional)
A relief valve can be attached as a block at the pump pipe at a device for single-line systems. It is directly flanged to the pressure and
return connection. The single-line block is equipped with a pressure relief valve, which enables the pressure line to be relieved as
required for single-line systems.
11.3.5 Pressure limiting valve (optional)
Optionally, a pressure limiting valve can be attached to the device for progressive and dual-line systems. It is available as component
for a customer-specific attachment in the entire system or as a module for direct attachment at the pump pipe. It has an opening
pressure of 280 bar.
