Omega CNiS8DH, CNiS32, CNiS16D, CNiS8DV MAXIMUM/PERCENT High Submenu, Control Type Output

Page 42

MAXIMUM/PERCENT HIGH SUBMENU:

Specify in percent, the maximum value (99) for control output. If the output is analog proportional (Current or Voltage), then the maximum voltage or current, in percent, is specified. If the output is time proportional (Relay, SSR, or Pulse), then the maximum duty-cycle, in percent, is specified.

Press d

Press b & c

Press d

12)Display flashes 1st digit of previous “Percent High” setting.

13)Use b and c buttons to enter a new value for “Percent High”.

14)Display shows STRD stored message momentarily and then advances to CTRL Control Type Submenu.

Example: On an Analog Output of 0-10 Vdc, a setting of %LO = 10 and %HI = 90, cause the minimum on the control output to be 1 V and the maximum on the control output to be 9 V. The same setting on a time proportional output, will cause 10% duty cycle for the minimum control output and 90% duty cycle for maximum control output. To disable %LO/HI, set LO to 00 and HI to 99. If %LO/HI is at other values than the default (%LO = 00, %HI = 99), SOAK is disabled.

*CONTROL TYPE OUTPUT:

(Relay, SSR, Pulse or Analog)

Press d 15) Display flashes ON.OF On/Off or PID PID.

Press b 16) Scroll through the available selections: “ON.OF” or “PID”. Press d 17) Display flashes STRD stored message momentarily and then

advances to AçTN only, if it was changed, otherwise press a to advance to AçTN Action Type Submenu.

The ON.OF control is a coarse way of controlling the process. The “Dead Band” improves the cycling associated with the ON.OF control. The PID control is best for processes where the set point is continuously changing and/or a tight control of the process variable is required. PID control requires tuning and adjustment of the “Proportional”, “Integral or Reset” and “Derivative or Rate” terms by a trial- and-error method. The instrument provides an "Auto Tuning" feature making the tuning process automatic, possibly optimum.

*If Analog Output (Current/Voltage) is your control Output 1, this menu i.e. CTRL type will not appear, instead 4-20 Current will be displayed.

Select ENBL for a 4-20 mA current (2-10 V Voltage) outputs or DSBL for a 0-20 mA current (0-10 V Voltage) outputs.

If 4-20 mA is enabled, %HI/LO setting will have no effect.

Both Current and Voltage control outputs are active simultaneously.
