22-7* Short Cycle Protection
When controlling refrigeration compressors, often there will be a need for limiting the numbers of starts. One
way to do this is to ensure a minimum run time (time between a start and a stop) and a minimum interval
between starts.
This means that any normal stop command can be overridden by the
Minimum Run Time
function (par.
22-77
Minimum Run Time) and any normal start command (Start/Jog/Freeze) can be overridden by the
Interval
Between Starts
function (par.22-76 Interval between Starts).
None of the two functions are active if
Hand On
or
Off
modes have been activated via the keypad. If selecting
Hand On
or
Off
, the two timers will be reset to 0, and not start counting until
Auto
is pressed and an active start
command applied.
22-75 Short Cycle Protection
Option: Function:
[0] * Disabled Timer set in par.22-76
Interval between Starts is disabled.
[1] Enabled Timer set in par.22-76
Interval between Starts is enabled.
22-76 Interval between Starts
Range: Function:
par.
22-77 s*
[par. 22-77 - 3600 s] Sets the time desired as minimum time between two starts. Any normal
start command (Start/Jog/Freeze) will be disregarded until the timer has
expired.
22-77 Minimum Run Time
Range: Function:
0 s* [0 - par. 22-76 s] Sets the time desired as minimum run time after a normal start command
(Start/Jog/Freeze). Any normal stop command will be disregarded until
the set time has expired. The timer will start counting following a normal
start command (Start/Jog/Freeze).
The timer will be overridden by a Coast (Inverse) or an External Interlock
command.
NOTE: Does not work in cascade mode.
