6.5. Operation of the ATICS® unit
A brief commissioning instruction for the skilled personal is enclosed with the documentation.
Please refer to the document TKA1443. For detailed instruction of the changeover and
monitoring unit ATICS® read the technical user manual TGH1443.
6.6. Use of the bypass circuitry (optional)
By using the optional bypass switch (S1) the changeover and monitoring module can be set into the bypass
mode. In this case the switch will bypass the ATICS® (N1) unit. The ATICS® switch can then be tested or
replaced without power interruption downstream to the changeover and monitoring module.
Next to the bypass switch S1 is a green and red indicator H1 as well as the auxiliary power supply T1.
The green indica
tor is showing that the ATICS® unit is in position “I”. Only if the green indicator is ON the
bypass circuitry can be operated. In a fault free condition line 1 is in use and voltage is applied.
The bypass switch S1 must be operated only if:
- The ATICS® switch
N1 is on position “I”
- The green indicator H1 is ON.
- If the red LED is ON or both are OFF there is a risk of short circuiting the supply.
The bypass switch must not be operated if the green indicator is OFF !
A failure to observe this may result in a short circuit when switching S1
to position “I+II” and
may result in the loss of power to the connected loads.
Important instruction:
If a power failure of line 1 occurs while the switch S1 is set to bypass mode
in position “II” the
switch must not be operated again! In this case the ATICS® unit must be manually switched to
position “0” using the Allen key wrench.
Before the clear cover of the ATICS® unit is being firmly closed the bypass switch S1 has to be set
to position “I” again. If this instruction is not being followed the ATICS® will automatically
changeover to line 2 as soon as the cover is being firmly closed. Closing the clear cover will
activate the automatic mode of the ATICS® unit.
After each and every switching operation the normal operating condition has to be verified and logged in a
protocol.
Only skilled persons may work or operate the changeover and monitoring module. Skilled
means, persons who are familiar with the assembly, commissioning and operation of the
equipment and have undergone appropriate training. Such persons must have read this manual
and understood all instructions relating to safety.
Turn the bypass switch continuously
from position “I” via “I+II” to position “II” to bypass the
ATICS® unit. Turn the bypass switch continuous
ly from position “II” via “I+II” to position “I” to
run the ATICS® unit again in the none-bypass/normal mode.
The time in which the bypass is acti
ve in position “II” must be minimized.
