3.“ALF.3=0” makes “SP 4” INDEPENDENT, with a level equal to the value inserted for “SP 4”.
“ALF.3=1” assigns “SP 4” to “SP 2”, placing it ABOVE “SP 2” by the amount entered for “SP 4”.
“ALF.3=2” places “SP 4” BELOW “SP 2” by the amount entered for“SP 4”.
“ALF.3=3” places “SP 4” ON BOTH SIDES OF “SP 2” by the amount entered for “SP 4”.
4.“ALF.4=0” makes Alarm 2 (Setpoint 4) a NON-LATCHING Alarm.
“ALF.4=1” makes Alarm 2 (Setpoint 4) LATCHING. This means that once Alarm 2 (Setpoint 4) is triggered it will
remain active until it is reset by pressing the ‘RESET” button one time or by grounding P2-11 when configuration bit
“ALC.8=1” is set.
Reset can also be accomplished via the optional RS-232 or RS-485 serial communication board.
