Appendix A
Analog Output Signalling (proportional or 2-state): menu level 0
Analog mode (the loop-current) can provide either:
• a 4 or 20 / 20 or 4 mA output, when 2-state mode is selected
1
or
• a 4 to 20 / 20 to 4 mA continuous signal proportional to the percent of the range
2
Upper Threshold Delay (2-state mode)
The Upper Threshold Delay controls the Activation delay: the amount of time that has to
pass uninterrupted with the probe covered to a level above the Upper Threshold Setting
before the timer expires. When the timer expires, the output signal complies with the
setting from Menu 08 for a covered probe. Whenever the level drops below the Upper
Threshold Setting before the timer expires, the timer is restarted.
As an extra identifier, an upward running A is displayed to the right of the value.
1. Set the loop-current control (Menu 07) to 2-state mode.
2. Set the rotary switch to 3.
3. Press the RED (+) or BLUE(–) button to increase or decrease the value.
or: Press and hold a button to start a repeat function.
or: Press and hold both buttons simultaneously to toggle the value between
minimum (0) and maximum (100).
1.
When FSH/FSL mode is selected at menu 1E, the mA signal is either 20 or 4 mA
2.
The continuous mA signal is available only when FPM mode is selected at menu 1E.
Notes:
•
To set values for Upper and Lower Threshold Delay, and Upper and Lower
Threshold Setting (2-state mode), the loop-current menu (07) must be in 2-state
mode.
•
The factory setting is FailSafe High mode, and 2-state mode is selected.
•
When the loop-current control is in analog mode, the LCD displays only - - - - for
these menu selections (only applicable in FPM mode, selected at menu 1E).
