I
risk of short circuit if "Enable bypass" light is ignored.
If ATICS® is not connected to the line to which the bypass switch is connected, a short circuit may oc-
cur between line 1 and line 2. The bypass switch may only be operated when the green "Enable
Bypass" light lights up.
If a voltage drop occurs on line 1 while the switch is set to "II" (=bypass), the switch must not be set to
position "I+II" or "I". In this case, the ATICS® device must be switched to position "0" or "I" manually us-
ing the Allen key. Only after doing this, the bypass switch can be set to position "I" while the transpar-
ent cover (manual mode) is open. Afterwards, the transparent cover can be closed to enable the auto-
matic mode. If the transparent cover is closed beforehand, the ATICS® device will automatically switch
back to line 2.
Conditions for operation with the bypass switch
• Wiring must be carried out according to „Connection example: ATICS® with bypass switch“ on
p. 34.
• The following must bet set in "Settings menu 6: Dig. input":
– 1. Function: Bypass
– 2. Response value: 0 V
– 3. t(on) response delay: 100 ms
– 4. t(off) delay on release: 100 ms
I
risk of electric shock when touching the contacts on line 1, 2 or 3.
Mains voltage at the contacts of line 1, 2 and 3. Only touch the insulated part of the connector.
9.5 Replacing the ATICS®
The plug connectors make it easy to replace the device if
• the ATICS® has reached the end of its service life or
• an event has occurred which jeopardises safety: e.g. overvoltage, short-circuit switching, com-
ponent failure.
I
risk of electrocution due to electric shock! Touching live parts of the system carries the risk of elect-
ric shock. Before installing and connecting the device, make sure that the installation has been de-
energised. If ATICS® is bypassed by an ATICS-BP-… bypass switch, the regulations which apply to
working on live parts must be observed.
