Mapping complex combinations of alarms to a relay
The following steps map a complex combination Alert alarm and/or Danger alarms to a
relay. Each alarm that triggers a relay is called a source. For this example, you map
channel 1 Alert alarm and channel 2 Danger alarm or channel 2 Alert alarm and channel 1
Danger alarm to a relay.
This can be shown with the following equation:
Relay 2 = (channel 1 Alert AND channel 2 Danger)
OR
(channel 2 Alert AND channel 1 Danger)
where
z
(channel 1 Alert AND channel 2 Danger) is ALM1MAP (the first alarm map) and is the
first relay source (RLYSRC1).
z
(channel 2 Alert AND channel 1 Danger) is ALM2MAP (the second alarm map) and is
the second relay source (RLYSRC2).
z
Relay 2 is RLY2MAP, which is the combination of the first relay source (RLYSRC1)
OR the second relay source (RLYSRC2).
Note: You can set up to six alarm maps.
Setting Relay 2 using this equation involves the following tasks:
1.
Set ALM1MAP to channel 1 Alert alarm AND channel 2 Danger alarm.
2.
Set ALM2MAP to channel 2 Alert alarm AND channel 1 Danger alarm.
3.
Set the RLY2MAP to the combination of ALM1MAP OR ALM2MAP.
Each of these steps is explained in the sections that follow.
To set ALM1MAP
1.
Move the highlight to MAPPING and press SEL.
