7.11.2 Set Up Mapping for an Analog Sensor Input
• Use the arrows
↑↓
to choose Map Sensor To Relay from the Map
Input/Sensor Menu, and press Enter
↵
.
• From the Select Sensor Menu, choose the input you want—for
example, Sensor_1 High Stpt —and press Enter ↵ .
Map Sensor to Control Relay
• On the Sensor-to-Relay Map screen, you may map the selected sen-
sor to either or both of the control relays (1-2). The example at right
shows Sensor_1 High Stpt mapped to Control Relay 1 .
To make changes to the mapping:
• If needed, press Enter ↵ to advance to the position directly
below the relay.
• Use the arrows
↑↓
to choose Y (Yes - Mapped to this relay) or
N (No - Not mapped), then press Enter ↵ .
• Press Enter ↵ to advance to the next position where you want
to make a change.
• Use the arrows
↑↓
to choose Y (Yes - Mapped to this relay) or
N (No - Not mapped), then press Enter ↵ .
• When finished, press Enter ↵ again.
Default Mappings - Analog Inputs to Control Relays
By default, analog inputs are not mapped to any control relay, as
shown in Table 31 .
Table 31 Default mapping of analog inputs to relays
Analog input By default, mapped to control relay:
Sensor_1 (none)
