iC-ALARM

The optional iC-ALARM interface (ordering no. 8005-065) enables to trans-
fer signals depending on three different critical operating conditions. Each
of the potential-free alarm outputs is directly coupled to a floating change-
over relay and is designed as an individual pin of the 15pins high-density
D-Sub connector. Thus all three alarm signals can be transfered simul-
taneously. The relays change their states instantly when the following
operating conditions are present:
ALARM OUT 1: Loss of clock reference at the currently active input
ALARM OUT 2: Loss of Main1 or Main2 (or circuit), only iDdp
ALARM OUT 3: Loss of the internal reference oscillator
Every of the above mentioned operating conditions activate also the red
front panel LED »ALARM set«.
The relays are normalled when the described operating conditions work
faultlessly. If a disturbance occurs, the according relay faills instantly.
The output contacts supply a max. switching power of 30 W with
30 V / 1A DC / AC peak. The type of the used relays is called TQ2-5V from
NAIS / Matsushita (http://www.nais-e.com/relay/index.html).
