Safety Instructions for Servicing

 Service work shall only be carried out by authorized service technicians.
 The operating mode selection switch must be put in the correct position with repair, mainte-
nance and set-up work. Remove the key to protect against unauthorized usage.
 The safety devices must be set by authorized service technicians.
 Do not replace or override the safety devices.
 Wear tight-fitting safety gloves when doing setup work to reduce the danger of pinching. Wear
a protective helmet when doing service work in the test stand pit to avoid impact injuries.
 Life-threatening electrical voltage! Only authorized electricians are allowed to work on the elec-
trical parts of the equipment based on valid electro-technical rules and guidelines. Before doing
any work on the test stand electrics switch off all voltage and secure against re-starting. Test
for absence of voltage! Cabinet contains components with storage charge. After switching off
all voltages life-threatening voltage can still be present for at least 5 minutes! Check for dis-
charge before starting work! Lock circuit box and store key securely. Hand out key only if
needed to authorized electricians.
 Errors and deviations from normal operating conditions are to be inspected only by trained
skilled workers who are authorized to do this kind of work. Circuits which are fed by an uninter-
ruptible power supply are still under voltage even after the test stand has been switched off
from the mains connection. The control has circuits which are tapped before the mains discon-
nection device of the test stand and are not voltage-free after switch off using the mains dis-
connection. All equipment which are connected before the mains disconnection device are
wired with the colors YELLOW or ORANGE. Pay attention to calibration instructions.
 Use suitable lifting device with sufficient load capacity to open heavy dyno components. Re-
moval and transport only by qualified skilled personnel. Adhere to all valid safety regulations and
relevant work protection guidelines. Lift dyno components only on the designated lifting points.
1.7

Danger Zone

During dynamometer operation no persons are allowed to stay in the danger zone. Minimum
distance is 1100 mm on all sides of the roller(s).
1.8

Safety Information about Tires

 Check tire pressure and do a visual check of the tires for any signs of damage.
 To avoid tire damage we recommend that test tires be used during the performance test.
 According to tire manufacturers, tires which have been used for performance testing shall not
be used for the road. Invisible tire defects may occur.
 No vehicles shall be tested which have snow tires, racing tires or retreaded tires!
 Pay attention that the rated speed for the tires is not exceeded!
 Check all wheel components to make sure they are tight before testing.

Safety Information about the Eddy Current Brake

Optionally available.
The eddy current brake can heat up significantly during long lasting usage. The brake rotors may
become red hot.
