Microsensor MPM4881 Operation Manual page 8

internationally advanced ARM processing chip. It can process
the process pressure through 1 current output, 1 voltage output,
5-relay output and 1 LED display.
1、Display
When MPM/MDM 4881 is powered on, it displays"MPM" for
seconds, then display real time pressure.
User can set the display (real time pressure, max.
switch point) at Basic Settings Menu. After MPM/MDM 4881 is
powered on, it can display real time pressure, corresponding
switch point or max. pressure.
2、Output
① Relay output
MPM/MDM4881 has 5-relay output. Each relay can set 1
switch point and 1 hysteresis. When pressure gets to "switch
point", relays will act. When pressure return back to "switch
point-hysteresis", relays back to normal.
② Set switch point
·Press corresponding button ,eg. "P1"
·Display switch point code, eg. "SP1"
·2 seconds later, it displays real time setting value
·Press"+"or"－"key to change value
"SP1"..."SP5"= Switch point 1...5
"HYS1"..."HYS5"= Hysteresis 1...5
