Appendix A
Lower Threshold Setting (2-state mode)
The Lower Threshold Setting is the % of range below which the probe is considered
uncovered. In order to switch the output signal, the corresponding delay time has to be
met (Menu 04).
The loop-current control (Menu 07) must be in 2-state mode for this menu to display the
Upper Threshold Setting in percent. As an extra identifier, a downward ramp 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 6.
3. Press the RED (+) or BLUE (–) button to increase or decrease the value.
or: Press and hold a button to start a repeat function.
Analog Signalling Mode
(
2-state): menu level 0
The factory setting is for FailSafe High mode
1
(selected at menu 1E). When no buttons are
pressed, the LCD displays the current mA value. Analog Signalling Mode (a mA reading
proportional to level) is not available when FailSafe High or FailSafe Low mode (FSH or
FSL) is selected.
2-state Signalling Mode provides a 4 mA or 20 mA output. The settings are relative to a
covered probe:
• C: Hi selects a 20 mA signal for a covered probe, which switches to 4 mA if the
probe becomes uncovered.
• C: Lo selects a 4 mA signal for a covered probe, which switches to 20 mA if the
probe becomes uncovered.
