Parameters
P113 Relay OFF Setpoint
Sets the process point at which the relay returns to its NORMAL state.
For most applications, the relay is reset at this point. For IN-BOUNDS and OUT-OF-
BOUNDS alarms, it is the low point in the specified range. This parameter is set to Span
(P007), even when another reading, such as volume, is shown on the LCD.
P115 Relay Interval Setpoint
The length of time in hours between flow samplers (if P111 = 41).
P116 Dead Band
The distance above and below the bound alarm setpoints
For IN-BOUNDS and OUT-OF-BOUNDS Relay Functions (P111 = 2 and 3 respectively), a
dead band prevents relay chatter due to material level fluctuations at both the upper and
lower setpoints.
