Satchwell IAC 600 - Control Modules; Controller Module (2 Stage)

LOGIC MODULES
(
Cont.
)
ROTATION MODULE
x 3
The Rotation module is used to rotate upto six di
g
ital inputs in
se
q
uence. Rotation is tri
gg
ered b
y
a di
g
ital pulse on the rotate input.
Onl
y
those inputs connected are rotated. This is t
y
picall
y
used to
rotate modular plant such as boilers, chillers, pumps etc to even out
the wear on the individual items of plant.
Current Lead

1 to 6 –
Rotate
Allows the module to be manuall
y
rotated. Each selection rotates to
the next item of plant.
On or Off Off
STOPWATCH MODULE
x 8
The Stopwatch module has a di
g
ital input that when set to on will run
the stopwatch. The stopwatch will stop when the input is set to off. A
second di
g
ital input on the module is used to reset the module to zero.
A t
y
pical use for this module is plant hours run, boiler/chiller rotation,
switchin
g
the lo
gg
in
g
module for timed lo
g
s etc.
Current Count
This parameter is usuall
y
used to review the current count but it also
allows the user to set an initial count value if re
q
uired.
0 to 10,000 0
Rollover Time
The di
g
ital output will produce a pulse at the set rollover time and the
stopwatch will reset to zero and start countin
g

COUNTER MODULE
x 8
The Counter module is used to count pulsed di
g
ital inputs on either the
risin
g
ed
g
e of the momentar
y
di
g
ital input or on both the risin
g
and
fallin
g
ed
g
es. The secondar
y
output will be pulsed each time a count
is made. This includes the fallin
g
ed
g
e if that has been set in the
counter. The secondar
y
di
g
ital input is used to zero the counter at a
time other than when the rollover count is reached.
Current Coun

This parameter is usuall
y
used to review the current count but it also
allows the user to set an initial count value if re
q
uired.
0 to 10,000 0
Rollover Count
At a preset rollover count the module will

0 to 10,000 1000
Count Rising and Falling Edges
Sets the module to count both the risin
g
and fallin
g

es of the pulsed
input.
Yes or No No

the main set value if reset is used.
–10,000 to 10,000 –
Integral Action Dumping On
The optimiser set point must be e

ual to the controller set value minus
the appropriate deadzone.
Integral Action Dumping Off
The optimiser set point must e
q
ual the controller set value.

Set Value
This parameter is used to set the desired controller set value.
–10,000 to 10,000 19
Set Value Minimum
This value sets the lowest set value the controller is allowed to use.
