check
Electrical 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 nal
installation, including possible lift to a high nal location. See Fig. 2
4) Leave space around IPS for air circulation ow. 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 nal 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 Ais opened, and SV is properly assembled.
ii.Check that port Bis 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
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 eld 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 dierent voltage for eld 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>

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 reected 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 C-110 C] on its surface, - then STOP IPS
and call Danfoss.

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.
a) Navigate from the Main Menu to Start by <Enter>
b) Select“Main Switch OFF”
c) Go to Main Menu
d) Navigate from the Main Menu to“Login”
e) Enter password“200”
f) Choose“Parameters”
g) Choose“Unit Cong”
h) Choose“Valve Settings”
i) Enter the number of purge solenoid valves connected to the IPS (factory setting is:8)
j) 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.
1. Navigate from the Main Menu to Start by <Enter>
2. Enter password “200”
3. Choose“Start”
4. Choose“Next Purge Point” and <Enter>
5. Press <X>, to go back to main screen
6. 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
