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 139). 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 HydroRanger 200 advances to and returns from the Failsafe Material
Level.
Relays (P100 to P119)
The HydroRanger 200 has one, 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 one,
three or six relays. See the
Relay
section on page 39.
Preset Applications (P100)
The HydroRanger 200 makes standard applications easier to program by providing an
extensive list of presets.
