Assembly
10/18 810.00113.0
4.4 Installation
4.4.1 Mechanical installation
1. Pre-assemble the oil level regulator in the mounting position.
2. Screw in screws by hand.
3. Then tighten with 9Nm tightening torque.
Additionally for the installation of an adapter:
1. Ensure the cleanliness of the thread of the compressor and adapter.
2. Assemble the INT280 adapter so that the hexagon of the inner part is flush mounted with the outer ring (see
note A in dimensions in mm in the Accessories chapter).
3. Mount the thus pre-assembled INT280 adapter to the compressor with the specified torque of the manufacturer.
4. Mount the INT280 oil level regulator with sealing ring to the adapter; mounting the screws hand-tight with the
included washers. Then tighten with 9Nm tightening torque.
4.4.2 Cable installation
Observe the following points when routing the connecting cables:
• Do not go below the bending radius permitted for the cable used.
• Fixate the cable suitably at sufficient distances.
• Route the cable with drip loop.
• The seal of the PG screw fittings is ensured only when approved cable cross-sections are used (see data sheet).
4.4.3 DP cable connections
• The "INT280-xxx" Diagnose can operate with the data of the compressor protection units INT69 Diagnose.
Coupling is by a DP-Y cable (see Accessories).
• If there is a network with an INT600 DM, only original DP cables from KRIWAN may be used.
• DP cables may not be modified or extended.
• If no DP cable is connected, then the DP protection needs to be mounted.
• DP cables may only be connected or disconnected when there is no voltage.
4.5 Before commissioning
• Before the oil level regulator is switched on for the first time, the oil level should already be at ¼ of the sight glass
to prevent the alarm relay from being deactivated.
• Before the refrigerating system is filled with refrigerant, the system and the connections of the Ölspiegelregulators
have to be checked for leaks.
The oil level regulator has to be installed in such a way that the sight glass points to the left or to the
right. Only the horizontal installation according to the data sheet is in the specified manner and thus
permitted.

5.1 Application information
5.2 Refill intervals
5.2.1 INT280 B
After the INT280 B is switched on, the alarm relay picks up after 3s, if no malfunction is present (closed-circuit
principle). Regardless of the oil level, a 20 second pause is activated to allow the oil to settle. If, thereafter, a too low
oil level is detected, the solenoid valve switches to oil injection in a specified cycle:
1st cycle: fill 5s / wait 5s,
2nd cycle: fill 10s / wait 10s,
3rd cycle: fill 20s / wait 20s...
If, after 135s, an adequate oil level has not been reached, the alarm relay drops out. The last filling cycle that has
been reached (fill approx. 30s and wait approx. 30s) stays active. If an adequate oil level has been reached, the
alarm relay picks up again after a waiting time, the filling cycle is reset.
If there is a device malfunction (e.g. low supply voltage), the alarm relay drops out and is locked, regardless of the
oil level, after approx. 5s. No filling procedure is performed.
The lock can be released by an open circuit of the voltage supply for at least 5s.
5.2.2 "INT280-xxx"
After the "INT280-xxx" is switched on, the alarm relay picks up after 3s, if no malfunction is present (closed-circuit
principle). Regardless of the oil level, a 2 second pause is activated, to allow the oil to settle. If, thereafter, a too low
oil level is detected, the solenoid valve switches to oil injection for the filling time (default 10s).
If the fill level has not been reached until then, the solenoid valve is switched off for the break time (default 20 % =
2s) and then switched back on for the filling time. This is continued until the fill level is reached.
If an adequate oil level has not been reached after the oil deficiency alarm delay has expired (default 120s), the alarm
relay drops out. Refilling oil is continued to be attempted. If an adequate oil level has been reached, the alarm relay
picks up again after a waiting time.
If there is a device malfunction (e.g. low supply voltage), the alarm relay drops out and is locked, regardless of the
oil level, after approx. 5s. No filling procedure is performed.
The "INT280-xxx" has its own monitoring system of the optical sensor. If there is a malfunction, the alarm relay is
locked and the error is signalled by the flash code.
If there is a soiling of the glass cone, this is signalled by the flash code when the warning threshold is exceeded. The
function continues to be ensured.
A cleaning should be carried out during the next general maintenance, see Chapter Cleaning.
If the soiling of the glass cone reaches a critical value, the compressor is switched off locked or the warning soiling
stage 2 is generated, depending on the setting.
The lock can be released by an open circuit of the voltage supply for at least 5s.
For proper operation, make sure that there is always enough oil in the oil reservoir and sufficient oil
pressure is available.
If there is a malfunction in the refrigeration circuit, in particular in cases where foreign particles, e.g.
soot, may get into the oil circuit, the oil and the corresponding filters need to be replaced. The oil
level regulator also needs to be replaced in case a cleaning of the prism of the oil level regulator
cannot be done.
The applications and the functional description are specified in the accompanying data sheet.

Functional description
12/18 810.00113.0
5.2.3 "INT280-xxx" Diagnose
By means of the diagnose port, data such as the last 20 errors, error counters, current status and switching
behaviours can be read out with the INTspector.
A variety of parameters to be adjusted for optimal adaption to the application. Refer to the data sheet on which
parameters these are.
5.3 Explanation of individual parameters
Parameter name
Filling cycle type With "fixed", the filling cycle runs with the set filling and break time. If the filling
cycle type is switched to "adaptive", the "INT280-xxx" calculates the optimal
filling and break times itself. The times are calculated so that the set nominal
filling period number is calculated.
Filling time Time that the solenoid valve is opened cyclically if there is an oil deficiency.
Break time Time that the solenoid valve is closed cyclically if there is an oil deficiency. The
time is specified in percent of the filling time.
Overfill time Once the fill level of the oil has been reached, the solenoid valve remains open
for the time set here.
Set number of filling periods With "adaptive" control, the oil level regulator calculates the times so that this
number of filling times is needed until the filling.
Oil deficiency alarm monitoring A choice can be made here whether the alarm delay of the compressor run
should be evaluated or not.
Oil deficiency alarm delay If a deficiency of oil is detected, this time is started. Once the time has elapsed,
the relay switched the compressor off. If the function "Alarm monitoring only
when compressor is running" is active, the time is stopped when the
compressor is at standstill. Once the compressor starts up again, it continues
to run.
External alarm via DP bus When the Diagnose devices are connected, a choice can be made here whether
an alarm from a different Diagnose device will also cause the alarm relay of the
oil level regulator to be switched off and that the alarm is displayed at the LED
of the oil level regulator.
Operating recognition via DP bus A setting can be made here whether the run detection should be evaluated or
not of a connected Diagnose compressor protection unit.
Behaviour monitoring A setting can be made here whether the behaviour monitoring should be active
or not.
Filling cycle time overrun coefficientWhen the DP bus run detection is active, the oil level regulator determines an
average filling cycle time. If this time is exceeded during a filling process for the
coefficient set here, a warning is generated.
Time overrun without filling
coefficient
When the DP bus run detection is active, the oil level regulator determines an
average time without filling process. If this time is exceeded during compressor
run for the coefficient set here, a warning is generated.
Soiling stage 2 The glass cone is monitored for soiling. A choice can be made here whether the
compressor should be switched off if the second soiling stage is exceeded.

Troubleshooting
810.00113.0 13/18
6 Troubleshooting
Malfunction Possible cause Solution
Oil level in the compressor too low
even if there is refilling
No oil in the oil reservoir Refill oil, find oil imbalance
Oil level in the compressor too low
even if there is refilling
Differential pressure is too low Check whether the differential
pressure between oil reservoir and
compressor is great enough; set
differential pressure valve.
Compressor is running even though
there is not enough oil in the
compressor for a longer time.
Alarm relay not in the alarm chain Correct the connection
Alarm relay pulls in even though
compressor is at standstill
No filling possible due to missing inlet
pressure
Use "INT280-xxx" Diagnose (run
detection possible and thus no alarm
when compressor at standstill)
