3.6 Unit Alarm Connections
The single form C relay is utilized to provide a dry contact closure for alarm
conditions. While the unit is energized, the alarm relay is energized. This allows
the unit to provide an alarm should the device lose DC power or becomes de-
energized.
The TTC-1000 monitors five conditions: Processor (DEVICE), Temperature
(TPROBE), Winding (WNDG), Communications Processor (CPROC) and Manual
Mode (MANUAL). The TTC-1000 allows the user to enable or disable any or all
of the alarm conditions, except the Communications Processor alarm, through
programming. The user can also program how each output reacts when an
alarm occurs.
Figure 3.14 a&b illustrates the connections.
The user can program each output in how it reacts when either a Processor or
Temperature alarm occurs. The user can set an output to pick up, drop out, or
stay in its current state when either alarm occurs.
