Siemens 200 instruction manual Relays P100 to P119, P072 Failsafe Level Advance

Parameters

Selecting HI, LO, or HOLd

1.Press FUNCTION to display the Auxiliary Function symbol.

2.Press ARROWS to scroll to the desired option.

3.Press ENTER to set the value.

Entering a Measurement

To enter a specific Failsafe Material Level within -50 to 150% of Span (P007), in Units (P005).

Relay reaction

The way in which relay programming reacts to the failsafe level depends on P129 Relay Failsafe (page 140). By default:

•Alarm relays have P129 = OFF and so react to the Failsafe Material Level.

•Control relays have P129 = dE and so de-energize the relay when the unit enters Failsafe mode regardless of the Failsafe Material Level.

P072 Failsafe Level Advance

Sets the speed the MultiRanger advances to and returns from the Failsafe Material Level.

Primary Index	Level
	1	*	Restricted	Advances to/from Failsafe Material Level as set by
				P003, P700 and P701.
Values
	2		Immediate	Failsafe Material Level assumed right away
	3		Fast Back	Failsafe Level Advance is restricted, return is
				immediate
	•	P003 Maximum Process Speed
	•	P070 Failsafe Timer
Related	•	P071 Failsafe Material Level
	•	P700 Max Fill rate
	•	P701 Max Empty rate

Relays (P100 to P119)

The MultiRanger has three or six relays (or digital outputs) used to control devices and alarms. While the number of devices is limited by the relays, all control functions are accessible through software and each parameter is indexed to the three or six relays. See the Relay section on page 41.

Preset Applications (P100)

The MultiRanger makes standard applications easier to program by providing an extensive list of presets.
