3.21.4 28-9* Injection Control
The injection ON/OFF signal is a forced close signal to the case controllers (to turn display cases off). The signal is distributed by following means-
hardwired through a digital output/relay or soft wired via bus by gateway or system manager.
28-90 injection_on
Range:
0*
[0 - 1]
28-91 Delayed Compressor Start
Range:
0*
[0 - 1]
Function:
The largest positive offset value that can be programmed into par. 28-81
ceeding the maximum reference value programmed into par. 3-03
is rounded to the nearest smaller integer. If a numerically larger value is entered the sum of the
offset and the setpoint is clipped to the value of the par. 3-03
Function:
The largest negative offset value that can be programmed into par. 28-81
ceeding the minimum reference value programmed into par. 3-02
is rounded to the nearest larger integer. If a numerically larger value is entered the sum of the offset
and the setpoint is clipped to the value of the par. 3-02
Function:
The sum of the setpoint of the drive (par. 28-83) and the offset programmed into 28-81
set
.
Function:
The setpoint of the drive excluding any offset programmed into par. 28-81
Function:
This parameter is read by LON Bus to convey the Injection ON /OFF signal to the case controllers.
If this parameter value is 0 then it means Injection OFF, if the parameter has a value 1 then it means
Injection ON.
Function:
If this parameter is set to 1, Delayed start of compressor is controlled by Injection Control feature
in association with par. 1-71 "Start Delay". If it is set to 0 then Delayed start of compressor is
controlled only by par. 1-71 "Start Delay". If par. 28-91 set to 1 and injection is OFF; start of com-
pressor is delayed by amount of time set in par. 1-71. If par. 28-91 set to1 and injection is ON then
start of compressor is not delayed. If par. 28-91 is set to 0, Injection Controller feature will not
interfere in delaying start of compressor. Delayed start of compressor is not active during Short
Cycle protection.
