7.1.2 "Measuring and switching" mode
Description:
Mode M2 "Measurement and switching" can be used to control limit switch relays for
signalling whilst simultaneously measuring the cleanliness of the oil in the hydraulic
system. This means that, in this menu, the user can switch external devices for warning
(alarm) by means of two relays. This could for example be a warning light at an
observation point.
Parameters for triggering these switching processes can be:
·
The flow rate
·
The cleanliness of the hydraulic fluid (given according to NAS or ISO standard)
Typical application
Signal switching to a control panel (observation point) on fully-automatic test rigs.
