11.2.13 INTTIM - Timer Interrupt
The timer interrupt function enables pulsed "stop/start"
operation by the actuator as a response to local and remote
control commands. This effectively increases the valve stroke
time and can be adjusted to prevent hydraulic shock (water
hammer) and flow surges in pipelines.
CL TIE - Closed-end Timer Interrupt Enable
OFF - Closed end Timer Interrupt is disabled.
ON -
Closed end Timer Interrupt is enabled.
ST CLS - Start Close, start position for closed end timer
interrupt
- Position below which the closed end timer
interrupt is active when closing. Can be set from 0
to 100% position. Must be set below SP CLS
(Stop Close).
SP OPN - Stop Open, stop position for closed end timer
interrupt
- Position above which the closed end
timer interrupt is inactive when opening. Can be set
from 0 to 100% position. Must be set below ST
OPN (Start Open).
CL ON - Close ON Time
The actuator run (ON) time around the closed end
of travel, when the closed end timer interrupt is
enabled and active. Can be set from 1 to 99
seconds.
CL OFF - Close OFF Time
The actuator Inhbit (OFF) time around the closed
end of travel, when the close end timer interrupt is
enabled and active. Can be set from 1 to 99
seconds.
OP TIE - Open end Timer Interrupt Enable
OFF - Opened end Timer Interrupt disabled.
ON -
Opened end Timer Interrupt enabled.
ST OPN - Start Open, start position for opened end timer
interrupt
- Position above which the opened end
timer interrupt is active when opening. Can be set
from 0 to 100% position. Must be set above SP OPN
(Stop Open).
SP CLS - Stop Close, stop position for opened end timer
interrupt
- Position below which the opened end
timer interrupt is inactive when closing. Can be set
from 0 to 100% position. Must be set above ST CLS
(Start Close).
OP ON - Open ON Time
The actuator run (ON) time around the opened end
of travel, when the opened end timer interrupt is
enabled and active. Can be set from 1 to 99
seconds.
OP OFF - Open OFF Time
The actuator Inhbit (OFF) time around the opened
end of travel, when the opened end timer interrupt
is enabled and active. Can be set from 1 to 99
seconds.
Blue denotes the active area for the closed end timer interrupt, when enabled.
Yellow denotes the active area for the opened end timer interrupt, when enabled.
