Emerson IP258 manual Parameter, Description, Default, value

Parameter	Description
No.
P400	Lower range value
	The mA set point for minimum PV in selected units
P401	Upper range value
	The mA set point for maximum PV in selected units
P402	Alarm action
	The is the value that the current will drive to on alarm
	action. The alarm action is programable and is selected
	from list (3.6/21mA/hold last reading).
P403	0-20mA/4-20mA
	The mA output is selectable by user,
	either 0 or 4 to 20mA
P410	Relay 1 Mode
	Select Relay function from a list (Off, Set Point,Desludge
	Alarm, Totaliser, Fault)
P411	Relay 1 On Point
	The value of the variable (as set in relay mode parameter)
	at which relay 1 turns on. Programmable by user
P412	Relay 1 Off Point
	The value of the variable (as set in relay mode parameter)
	at which relay 1 turns off.
P413	Relay 1 Min On Time
	A programmable parameter for the minimum on time
	of relay 1. This is to overcome slugs of clear liquor at
	the start of desludge cycles
P414	Relay1 Max On Time
	A programmable parameter for the maximum on time
	of relay 1. This is to ensure, for example, a pump does
	not continue to run due to a faulty signal from sensor.
P420	Relay 2 Mode
	Select Relay function from a list (Off, Set Point,Desludge
	Alarm, Totaliser, Fault)
P421	Relay 2 On Point
	The value of the variable (as set in relay mode parameter)
	at which relay 2 turns on. Programmable by user
P422	Relay 2 Off Point
	The value of the variable (as set in relay mode parameter)
	at which relay 2 turns off. Programmable by user
P423	Relay 2 Min On Time
	A programmable parameter for the minimum on time
	of relay 2. This is to overcome slugs of clear liquor at
	the start of desludge cycles
P424	Relay 2 Max On Time
	A programmable parameter for the maximum on time
	of relay off. This is to ensure, for example, a pump does
	not continue to run due to a faulty signal from sensor.
P415	Relay 1 Min Off Time
P425	Relay 2 Min Off Time
