NOTICE
Lubricating a dry running machine (compression chamber).
Risk of damage to the machine!
●Do not lubricate the compression chamber of the machine with oil or grease.
CAUTION
During operation the surface of the machine may reach temperatures of more than 70°C.
Risk of burns!
●Avoid contact with the machine during and directly after operation.
CAUTION
Noise of running machine.
Risk of damage to hearing!
If persons are present in the vicinity of a non noise insulated machine over extended periods:
●Make sure that ear protection is being used.
●Make sure that the installation conditions (see Installation Conditions [➔9]) are met.
●Switch on the machine.
●Make sure that the operating conditions comply with the Technical Data [➔40].
As soon as the machine is operated under normal operating conditions:
●Measure the motor current and record it as reference for future maintenance and trouble-
shooting work.
7.1 Relief Valve Adjustment
The factory setting of the relief valve is set at 600 hPa (mbar) absolute for a permanent usage. In
case of cycling one, can be adjusted down to 450 hPa (mbar) absolute.
To proceed, install the vacuum pump on a pneumatic bench with an absolute pressure sensor, an in-
let valve and, if available, a volume flow sensor set at the outlet.
●Remove the black cap.
●Unlock the relief valve position by unscrewing the small hexagon socket bolt (with hex key 2).

7 | Commissioning
16 | 44 Instruction Manual MINK MB 0018 A_EN_en
●Fully open the valve (decrease the spring resistance) by a clockwise rotation. Fully close the bench
inlet valve so that fresh air comes in by the relief valve only (volume flow sensor mentions 0 lpm).
●Adjust the relief valve position by closing the valve (increase the spring resistance) by a counter-
clockwise rotation to achieve 450 hPa (mbar) absolute +/- 5 hPa.
●Lock the relief valve position by screwing the small hexagon socket bolt.
●Reposition the black cap.
7.2 Standard Version
The machine starts automatically with maximum speed as soon as electrical power is supplied.
7.3 Version with Analog Speed Control
The electronic is automatically activated as soon as electrical power is supplied.
The speed can be controlled by a potentiometer connected to terminal 1 (KL15) on the HDSC con-
nector (CON).
Observe the following diagram to adjust the speed.

Commissioning | 7
Instruction Manual MINK MB 0018 A_EN_en 17 | 44
7.4 Version with CAN-Communication
The CAN communication and protocol are based on the following standards:
●ISO 11898 for hardware,
●SAE J1939 as vehicle standard for the software.
The CAN address coding is using the Intel protocol with Little Endian format.
The machine is controlled via CAN communication (see CAN Protocol [➔37]). The CAN control mes-
sage send all necessary signals and reference values to the machine.
There are two different operating modes.
The speed control mode controls the speed of the machine.
The mass flow control mode controls the speed of the machine depending on the mass flow. For
mass flow control mode, the machine must be equipped with an air mass flow sensor. In case of a
failure of the air mass flow sensor the machine switches automatically to speed control mode.
Terminal 1 (KL15)
NOTE
The KL15 must be powered with the same voltage as the +Vbatt (20-32VDC with a nominal volt-
age of 24VDC).
High voltage level on terminal 1 (KL15) switches on the internal power supply of the machine. After
switching on, the machine waits 10seconds for a valid CAN control message before a CAN failure
will be detected.
In case of a voltage level below 1.2V on terminal 1 (KL15) the machine decelerates to a speed of 1800
min-1. After 10seconds the machine stops. After further 2.5seconds the internal power supply of the
machine switches off.

7 | Commissioning
18 | 44 Instruction Manual MINK MB 0018 A_EN_en
CAN Status Message (Actual Values)
One second after startup, the machine sends every 50ms a CAN status message with actual values.
If the machine receives a CAN control message before the first second after startup the machine
sends the CAN status message immediately.
Power-On Bit
After startup a power-on bit is set in the CAN status frame for one second. The power-on bit can be
used to identify unexpected resets/restarts.
Loss of CAN Communication
If a loss of CAN communication occurs the reference value for mass flow will be set to 100g/min. A
loss of CAN communication will be detected if no valid CAN control message have been received for
500ms. As soon as the CAN communication is available again the machine switches to normal oper-
ation immediately.
Speed reduction by temperature
The maximum speed of the machine depends on the electronic temperature to ensure safe opera-
tion of the machine at any temperatures.
The machine will reduce the speed if the electronic temperature is too high even if the reference
speed value is higher than the actual speed. The speed reduction resulted from the electronic tem-
perature is indicated by the sixth bit in the CAN status frame. There will be no indication on the sixth
bit if the actual speed limited by the electronic temperature complies with the maximum speed.
Loss of air mass flow sensor
At loss of the air mass flow sensor, the software switches automatically into the speed control mode
with the predefined speed pre-control value.
Without or in case of loss of air mass flow sensor, the actual air temperature (given by the CAN Actu-
al Values) is 214°C by default.
The loss of air mass flow sensor is visible in the CAN Status bit (see CAN Protocol). This failure is au-
tomatically reset as soon as new values are received from the air mass flow sensor. Without air mass
flow sensor, the bit 2 of the diagnostics is automatically set to 1.
Over current protection
The electronics is protected against a blocked rotor or overload by an overcurrent protection. If an
overcurrent is detected the motor stops immediately. The bit 7 “overcurrent” in the CAN Status
frame is set for about 2 seconds.
One second after the stop of the motor the electronic tries to restart the motor automatically. If the
overcurrent error occurs one more time, the motor stops again and the error bit in the can status
frame stays on.

Commissioning | 7
Instruction Manual MINK MB 0018 A_EN_en 19 | 44
Plausibility check
A blocked rotor cannot be detected under all conditions by an overcurrent detection. Therefore, an
additionally plausibility check is implemented.
The plausibility check checks different ratios inside the motor controller. If a plausibility check error
occur the motor stops immediately and the bit 5 “plausibility error” in the CAN Status frame is set.
The timing for the error bit and the restart is identical to the overcurrent protection.
