Danfoss 084H5001 Intelligent Purging System
Product Information: Intelligent Purging System (IPS 8)
Ammonia
The Intelligent Purging System (IPS 8) is a purger unit designed
for use with ammonia systems. It is equipped with the MCX15B2
controller for efficient operation and control.
Features:
- Integrated MCX15B2 controller
- Designed for ammonia systems
- Allows for purging of gas lines
- Includes temperature and pressure sensors
- Easy navigation and configuration
Specifications:
- Power Supply: 230V AC, 1ph
- Frequency: 50Hz (code: 084H5001), 60Hz (code: 084H5002)
- Compliance: CE
Installation Requirements:
- Ensure proper mechanical installation as per Danfoss instructions
- Maintain horizontal alignment within 2 degrees to IPS top cover
- Keep the purger unit in an upright position at all times
- Provide sufficient space around the IPS for air circulation flow
- Inspect gas lines for possible dirt
Electrical Check:
- Verify connections to field-connected purge point solenoids and ICFD solenoid (if used)
- Coils voltage should be the same as the main power supply
- If field-connected solenoids have different voltage, refer to Fig. 9 for further instructions
Product Usage Instructions
-
Perform the mechanical and refrigeration check as per the instructions provided.
-
Ensure the IPS controller (MCX15B2) is properly set up.
-
Switch ON QS1, QM2, and QM4 in the electrical panel (refer to Fig. 10).
-
Check the temperatures before starting the compressor. They should be within the specified range (+/-1 K).
-
If temperatures are not within the range, check cables and connections of pressure and temperature sensors.
-
Navigate to the Main Switch parameter and select Start. Then select Main Switch ON.
-
Monitor the compressor operation and observe pressure and temperature changes on the main screen.
-
If the compressor runs for 15-25 minutes without significant pressure and temperature changes, and becomes very hot on its surface (90°C-110°C), stop IPS and contact Danfoss for assistance.
-
To configure the number of purge solenoid valves connected to the IPS, follow the steps below:
-
Navigate from the Main Menu to Start.
-
Select Main Switch OFF.
-
Go to Main Menu.
-
Navigate from the Main Menu to Login.
-
Enter password 200.
-
Choose Parameters.
-
Choose Unit Config.
-
Choose Valve Settings.
-
Enter the number of purge solenoid valves connected to the IPS (factory setting is: 8).
-
Go back to Start and choose Main Switch ON, and return to the main screen.

Mechanical / Refrigeration check
-
Verify that IPS 8 purger is installed, wired, and piped as per Danfoss instructions
-
Horizontal alignment requirements must be within 2 degrees to IPS top cover. See Fig. 1
-
The purger unit should be always kept in an upright position – from receipt to final installation, including possible lift to a high final location. See Fig. 2
-
Leave space around IPS for air circulation flow. Do not install it right up to a wall. See Fig. 3
-
Inspection of possible dirt in gas lines. See Fig. 4
- For purge point connect gas line a slope towards the IPS8 purger, must be observed.
- No liquid traps
-
Remember to remove rubber plug. See Fig. 5.
-
Carry out proper vacuum on the purge point connect gas line and R717 side of IPS 8 purger. The R717 side of IPS 8 purger must be pressurized prior to the IPS 8 being put into operation.
-
Before connecting power supply to IPS let it stand upright for min. 6 hours after it has been placed at its final location
-
After mechanical installation, but before connecting power supply IPS, please check:
- If Danfoss drain valve used (Type SV or ICF with ICFD), then check:
- SV: See Fig. 6a
- Check throttle valve A is opened, and SV is properly assembled.
- Check that port B is closed by bolt.
- ICFD: See Fig. 6b
- Check stop valves
- Check coil is installed on solenoids (Solenoid for ICF w/ICFD (DO6) – if used)
-
Open stop valves D, as we have vacuumized the pipes before. Open manually one of purge point solenoids E. See Fig. 6a and 6b
For general mechanical installation guidance/practice. See Fig. 6c
Electrical check3 -
Check Main power supply. See Fig. 7
- 084H5001, IPS 8: 230 V, AC 50 Hz
- 084H5002, IPS 8: 230 V, AC 60 Hz
- Power to be connected to Main switch: QS1 and Terminal: XT0
- Terminals on QS1
- 3, L2 – Line phase
- 1, L1 – Neutral
- Terminal XT0
- PE – Earth
-
Check connections to field connected Purge point solenoids and ICFD solenoid (if used) See Fig. 8a and 8b
- Coils voltage. Same as Main power supply. No further action needed.
- At different voltage for field connected solenoids coils. See Fig. 9
IPS controller (MCX15B2) setup
After Mechanical / Refrigeration check, the conditions for startup must be checked. See Fig. 10 for overview of Electrical Panel and location of Thermal magnetic miniature circuit breakers
-
Switch ON:
- QS1, QM2 and QM4. See Fig. 10
- QS1, QM2 and QM4. See Fig. 10
-
Before start of compressor, temperatures needs to be checked. Should all be within: +/-1 K⁰ (OK) – if OK then go to
If Temperatures are not within: +/-1 K⁰ then check cables and connections of pressure and temperature sensors. (NOK)
-
Preparation for start compressor
-
Switch ON – See Fig. 10
-
QM1 and QM3 Below (E10, System is OFF and the icon ) inform that MainSwitch is OFF
-
Navigation to Main Switch parameter
-
-
Select “Start”
-
Select “Main Switch ON” and
Go to Main Screen and watch compressor in operation and pressure/temperature changing. As compressor is in operation, pressure and temperature is changing, after about 15-25 minutes we should observe changes as reflected on below screens.
See development below from left to right
If the compressor is running for 15-25 minutes, without pressure and
temperature really changing
(example below) and compressor then becomes very hot [90 0C-110 0C] on its
surface, – then STOP IPS and call Danfoss.
IPS MCX controller – Quick start
Basically, the IPS with the built-in MCX controller, only need one setting, How many Purge points?See steps below for how to navigate to the parameter for entering how many Purge points which is connected.
- Navigate from the Main Menu to Start by
- Select “Main Switch OFF”
- Go to Main Menu
- Navigate from the Main Menu to “Login”
- Enter password “200”
- Choose “Parameters”
- Choose “Unit Config”
- Choose “Valve Settings”
- Enter the number of purge solenoid valves connected to the IPS (factory setting is:8)
- Go back to Start and chose ‘Main Switch ON’, and go back to main screen
See development below from left to right
IPS MCX controller – Quick start
It can be useful during commissioning to quickly move the next Purge point, in
order not to wait to IPS internal time cycle between purge points.
See steps below for how to navigate to the parameter in question.
- Navigate from the Main Menu to Start by
- Enter password “200”
- Choose “Start”
- Choose “Next Purge Point” and
- Press
, to go back to main screen - Check that Purge Point has been changed to the next one. (below example from Purge Point 3 to Purge Point 4)
See development below from left to right
It is important that the support construction is level to ensure the internal liquid trap is properly filled. Angle to horizontal < 2 degrees
