Some notes on some of the parameters not mentioned specifically in section 9.2, 9.3:
Max capacity change (Plant \ Page 1)
This parameter is used to limit how quickly the regulation is allowed to change the capacity setpoint. This can
be used to match the regulator in the ACP LINK to a regulator on customer side.
Max no. of alarms in timespan window and Alarm timespan window size (Plant \ Page 1)
These two parameters are used for automatic alarm reset and indicate the maximum amount of consecutive
equal alarms within a certain time frame that will be reset automatically. If the number of alarms in the time
frame is equal to or above the parameter set, then the alarm will require manual reset.
Alarm auto-reset delay time (Plant \ Page 1)
The delay time to automatically reset an alarm after the conditions have returned to normal. The values in line
5, 6 and 7 function together to make up alarm handling.
Total current high warning and alarm (Plant \ Page 1)
Parameter to set high warning and alarm limits for the total current (sum of all motor currents). A warning will
initiate the capacity limiter.
Suction superheat low and high warning and alarm (Plant \ Page 3)
Parameter can be modified to change the limits for surveillance of suction gas superheat.
Pressure and temperature sensors low and high signal limits
(Plant \ Page 3)
Parameter to modify the limits for the surveillance of high and low signals of the pressure and temperature
sensors used on the oil and economizer system module (CM-IO) and the electrical panel IO-module (M172).
Max motor speed change (Comp./Motor \ Page 2
)
Parameter to limit how quickly the motor speed setpoint will be changed. Used to match the ramp time on the
variable speed drive.
