OPERATION MULTI GAUGE CONTROLLER
3.4.1.1 SETPOINTS MENU
This parameter group allows you to conigure the switching of relays functions. The MG15 is equipped
with 10 relays which are switched depending on the measured pressure. Fig. 3.7 shows the set-
points behaviour:

Refer to chapter 2.5.5 to conigure connections.
To prevent multiple changes of the setpoint status when vacuum reaches the setpoint, histeresis
has been introduced which width is controlled by the Setpoint HI and Setpoint LO parameters:
• Setpoint HI – the level of vacuum which will be signalled by switching off the Setpoint diode
connected with a given measurement channel. If a vacuum measurement channel has been
connected with a given Setpoint (device relay output), then after reaching that value the relay
contacts at the output will be opened.
• Setpoint LO – the level of vacuum which will be signalled by switching on the Setpoint diode
connected with a given measurement channel. If a vacuum measurement channel has been
connected with a given Setpoint (device relay output), then after reaching that value the relay
contacts at the output will be closed.
