Page 11: Neutral Zone Mode
D145H4502 Ed. 01 Neutral zone mode WITHOUT FREQUENCY CONVERTER In this mode, a neutral zone is defined, whose lower limit is the Set Point minus the bandwidth, and whose upper limit is the Set Point plus the bandwidth. While the reading of probe 1 remains in that zone, no stages or compressors are connected or disconnected. -
Page 12: Pump Down
D145H4502 Ed. 01 WITH FREQUENCY CONVERTER Operation is the same as in the previous point, but modulating the power of compressor 1 with the converter while it remains in the neutral zone using a PID control. Near the upper limit, the compressor operates at its maximum capacity, and if said limit is exceeded, more stages/ compressors are added, in accordance with the interval defined in t02, until returning to the neutral zone. -
Page 13: Fan Control
D145H4502 Ed. 01 Fan control Proportional mode WITHOUT FREQUENCY CONVERTER The controller activates (red line) or deactivates (green line) the different fans available in a linear manner depending on the reading obtained in probe 2 until the Set Point (E01) is reached again, as shown in the following figure. The delays t05 to t08 must be accounted for. -
Page 14: Neutral Zone Mode
D145H4502 Ed. 01 Neutral zone mode WITHOUT FREQUENCY CONVERTER In this mode, a neutral zone is defined, whose lower limit is the Set Point minus the bandwidth, and whose upper limit is the Set Point plus the bandwidth. While the reading of probe 2 remains in that zone, no fans are connected or disconnected. -
Page 15: Floating Condensation
D145H4502 Ed. 01 WITH FREQUENCY CONVERTER Operation is the same as in the previous point, but modulating the power of the fans with the converter while it remains in the neutral zone using a PID control. Near the upper limit, the fans operate at their maximum capacity, and if said limit is exceeded, the capacity is kept at its maximum until returning to the neutral zone. -
Page 16: Alarms
D145H4502 Ed. 01 Alarms IMPORTANT: The alarms that cause compressors and fans to stop will do so in a sequential manner, with a delay of 5 seconds between stops. LOW AND HIGH PRESSURE ALARM DUE TO DIGITAL INPUT PRES TEMP When the digital input I5 or I6 is activated, the message HPA (High) or LPA (Low) is shown on screen, the alarm relay is activated (if available) and the compressors are stopped. -
Page 17: Remote Disconnection
Connectivity The AKO-D14545-C model has a port for RS485 (MODBUS) data connection, which enables remote management via the AKO XaviP Edge gateway and the akonet.cloud platform. A different address must be assigned to each unit on the same network. This address is defined by parameter b20. -
Page 18: Parameter Setup
D145H4502 Ed. 01 Parameter setup Through the programming menu users can set different parameters to adjust the operation of the controller to the needs of their installation. Programming Menu It allows changing the unit’s operating parameters. To access the programming menu, press the SET button for 10 seconds, or until the “PRG” appears on the screen. IMPORTANT: If the password function has been configured, the system will demand entering the password programmed in L5. -
Page 19: Parameters
D145H4502 Ed. 01 Parameters The unit’s operation parameters are organized into groups or families according to their function. The Def. column shows factory-set default parameters. The pressure values featured on the table are expressed in bar and those for temperature in ºC. If the wizard meanwhile selects another set of units (parameter C09), the unit will make the conversion automatically. - Page 20 D145H4502 Ed. 01 Level 1.- CONDENSATION CONFIGURATION PRES TEMP Description Units Min.
