Figure 21 - Alarm Relay Example
If Relay B Mode is set to
CON
(see
Relay B Mode
), then Relay B will
function identically to Relay A. Relay B settings appear in the CONFIG
menu list automatically.
When value rises to
≥
1.000 µS, relay closes, until
value falls back to
≤
0.950 µS.
When value falls to
≤
1.000 µS, relay closes, until
value rises back to
≥
1.050 µS.
