Operating State Wir On-Delay Outputs/Contacts - Zander Aachen SCB Serie Betriebsanleitung

Safety Time Control Device
2. to 4. Operating state
In the operating state, the display shows the delay time currently stored in the SCB. The
three LEDs I11, I12 and Out provide information about the current status of the inputs and
outputs.
INFO:
Picture 2: Current delay time is 2.6 s. Inputs and outputs are not activated
Picture 3: Inputs l11/l12 are activated, outputs are not activated
Picture 4: Inputs l11/l12 and outputs are activated
5. Requesting the safety function
Through the opening of the safety circuit, the non-delayed outputs/contacts are immedia-
tely switched off and the parametrized delay time is started. The blinking Out LED as well
as the countdown shown on the display provide information on the running delay time.
INFO: The countdown is used only for monitoring. Deviations from the actual delay time
can occur especially in long delay times. This function is available for all variants with a
time range from 0.0 to 99 seconds.
6. Safe state
At the end of the delay time, the delayed outputs/contacts switch off and the currently sa-
ved delay time is again shown on the display.
15.2 Operating state with On-delay outputs/contacts
1. Power-On
After the supply voltage is applied, the SCB carries out a self-test (duration approx. 9 se-
conds). At the same time, each individual segment is controlled on the display, whereby
the display can be checked for possible errors.
TIP: Checking the display before re-parametrising avoids possible incorrect settings due
to display errors.
2. Operating state
In the operating state, the display shows the delay time currently stored in the SCB. The
three LEDs I11, I12 and Out provide information about the current status of the inputs and
outputs.
