ICN77000 Series Controller - Ramp and Soak/Analog Output

Ramp & Soak

Display	Action	Response
	Press MENU Press ENTER	1) Press MENU, if necessary, until the "raMp soac" prompt appears. 2) Display advances to "Ramp Enable/Disable" submenu.
	Press ENTER Press MAX Press ENTER	RAMP ENABLE/DISABLE SUBMENU: 3) Display flashes "enbl" or "dsbl". 4) Scroll through the available selections: Enable or Disable. 5) Display flashes "strd" message and advances to "Soak Enable/Disable" menu.
	Press ENTER Press MAX Press ENTER	SOAK ENABLE/DISABLE SUBMENU: 6) Display flashes "enbl" or "dsbl". 7) Scroll through the available selections: Enable or Disable. 8) Display flashes "strd" message and advances to "Ramp Value" menu.

Note: Ramp & Soak provides users with the flexibility to slowly bring the process variable to the desired set point. Ramp & Soak Values is specified in HH.MM format. This value indicates the time specified to bring the process variable to Setpoint 1. Once set point is reached, the PID takes over and the process variable will be controlled at the desired set point indefinitely. If soak is enabled, PID will control the process variable at the specified setpoint for the duration of soak time and then will turn off Output 1. To start a new ramp/soak cycle, reset the controller by pressing MENU and then MIN button. An active ramp/soak will change SP1 one degree above the PV and will cause the most significant digit to blink. The SP1 will be incremented by one degree until it reaches the original SP1. The minimum ramp time must be at least twice the time that it will take the PV to reach the SV with OUT 1 fully ON.

	Press ENTER Press MAX & MIN Press ENTER	RAMP VALUE SUBMENU: 9) Display flashes 1st digit of previous "raMp" value. 10) Press MAX and MIN buttons to enter a new "raMp" value 11) Display flashes "strd" message and advances to "Soak Value" menu.
	Press ENTER Press MAX & MIN Press ENTER	SOAK VALUE SUBMENU: 9) Display flashes 1st digit of previous "soak" value. 10) Press MAX and MIN buttons to enter a new "soak" value 11) Display flashes "strd" message and advances to the "Analog Output"

Note: The ramp and soak time is 00:00 to 99:59 i.e. HH.MM.(from zero to 99 hours and 59 minutes)
During Ramp & Soak do not perform any operations or settings before first stopping it. Any alarms or other output isdisabled during this time.

3.3 Available Options
The Controller may be ordered with one of the three following options:
1) Analog Output: This option provides additional flexibility to transmit the equivalent value of process variable to other devices using a 4 to 20 mA current loop or 0-10 volt signal.
2) Communication Option: This option makes the controller a very powerful instrument providing the user with even greater capability since all the parameters can be transmitted via a personal computer.
3) Remote Set Point: One of the three already stored set points can be activated.

Analog Output Option

Display	Action	Response
	Press MENU Press ENTER	1) Press MENU, if necessary, until the "ANLG 0UT" prompt appears. 2) Display advances to "Analog Type" submenu.
	Press MENU	IF THE ANALOG OUTPUT OPTION IS NOT INSTALLED, THE CONTROLLER WILL SHOW "not InSt" Press MENU, if you receive the "not installed" message and advance to the "Communication" submenu.
	Press ENTER Press MAX Press ENTER	ANALOG TYPE SUBMENU: 3) Display flashes "volt" or "curr". 4) Scroll through the available selections: Volt or Current. 5) Display flashes "stored" message and advances to "Reading 1" of the Output Reading submenu.
	Press ENTER Press MAX & MIN Press ENTER	READING 1 6) Display flashes 1st digit of previous Reading 1 value. 7) Enter "Reading 1" value 8) Display advances to "Out."
	Press ENTER Press MAX & MIN Press ENTER	OUT 1 9) Display flashes 1st digit of previous Out1 value. 10) Enter "Out 1" value 11) Display advances to "Reading 2"
	Press ENTER Press MAX & MIN Press ENTER	READING 2 12) Display flashes 1st digit of previous Reading 2 value. 13) Enter "Reading 2" value 14) Display advances to "Out.2"
	Press ENTER Press MAX & MIN Press ENTER	OUT 2 15) Display flashes 1st digit of previous Out 2 value. 16) Enter "Reading 1" value 17) Display advances to the "Communication Option" menu.
Note: The above example is for 0-10 of the entire range of the process input and analog output. For 0-20mA output all you need is to set OUT2 to 20.00.
