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

1) Verify that IPS 8 purger is installed, wired, and piped as per Danfoss instructions 2 )Horizontal alignment requirements must be within 2 degrees to IPS top cover. See Fig. 1 3 )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 4) Leave space around IPS for air circulation flow. Do not install it right up to a wall. See Fig. 3 5) Inspection of possible dirt in gas lines. See Fig. 4
a. For purge point connect gas line a slope towards the IPS8 purger, must be observed. b. No liquid traps 6) Remember to remove rubber plug. See Fig. 5. 7) 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. 8) Before connecting power supply to IPS let it stand upright for min. 6 hours after it has been placed at its final location 9) After mechanical installation, but before connecting power supply IPS, please check: a. If Danfoss drain valve used (Type SV or ICF with ICFD), then check: b. SV: See Fig. 6a
i. Check throttle valve A is opened, and SV is properly assembled. ii. Check that port B is closed by bolt. c. ICFD: See Fig. 6b i. Check stop valves ii. Check coil is installed on solenoids (Solenoid for ICF w/ICFD (DO6) if used) 10) 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 check

11) Check Main power supply. See Fig. 7 a. 084H5001, IPS 8: 230 V, AC 50 Hz b. 084H5002, IPS 8: 230 V, AC 60 Hz c. Power to be connected to Main switch: QS1 and Terminal: XT0 i. Terminals on QS1 1. 3, L2 Line phase 2. 1, L1 Neutral ii. Terminal XT0 1. PE Earth
12) Check connections to field connected Purge point solenoids and ICFD solenoid (if used) See Fig. 8a and 8b a. Coils voltage. Same as Main power supply. No further action needed. b. 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 13) Switch ON:
a. QS1, QM2 and QM4. See Fig. 10 14) Before start of compressor, temperatures needs to be checked. Should all be within:
+/-1 K (OK) if OK then go to 15)

If Temperatures are not within: +/-1 K then check cables and connections of pressure and temperature sensors. (NOK)

15) Preparation for start compressor a. Switch ON See Fig. 10 i. QM1 and QM3
Below (E10, System is OFF and the icon

) inform that MainSwitch is OFF

16) Navigation to Main Switch parameter a. <Enter> b. Select “Start” c. Select “Main Switch ON” and <Enter>

User Guide | Intelligent Purging System (IPS 8) Ammonia 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.
