Errors Localization and remedy
Short circuit between
control voltage
connection (24 V) and
motor cable connection
(0 V) or housing
(section/curve modules)
The short circuit may be between the control voltage connection
(24 V) and the motor cable connection (0 V) or between the control
voltage connection (24 V) and housing (section/curve modules).
1.
Loosen and isolate one side of the ground connection line in the
curve module to which the control cabinet is connected.
557 186-133
2. Now measure the resistance between the control voltage
connection (24 V) and the motor cable connection (0 V).
R = ∞
The short circuit is located between the control
voltage (24 V) and housing (section/curve modules)
connection.
R < 1 kΩ
The short-circuit is located between the control
voltage connection (24 V) and the motor cable
connection (0 V).
3. Loosen the control voltage connection (24 V) at each end of the
system. This divides the system electrically into two parts.
4.
Measure the resistance of every half of the system. The short circuit
is located in the half of the system with a resistance of < 1 kΩ.
5. Loosen the control voltage (24 V) connection in the middle of the
half with the short-circuit.
6. Repeat step 4.
7. Repeat this until you have localized the section/curve module with
the short-circuit.
Short circuit between
control voltage
connection (24 V)
and motor cable
connection (28 V)
1. Loosen the control voltage connection (24 V) at each end of the
system. This divides the system electrically into two parts.
2.
Measure the resistance of every half of the system. The short circuit
is located in the half of the system with a resistance of < 10 Ω.
3. Loosen the control voltage (24 V) connection in the middle of the
half with the short-circuit.
4. Repeat step 2.
5. Repeat this until you have localized the section/curve module with
the short-circuit.
