Timed Event Relays
NOTE: Timed Event Relay is only available when options board is
connected.
If you will be controlling external devices through the relays on the
options board and timed events, you must first connect the external
devices to the ATD/TD and then program the events.
The 4 relay contacts are rated to switch 10 W (maximum). Do not
exceed 50V or 0.5A. External devices include external switching
valves, audible alarms, very small motors, etc. that can be controlled
using these timed events.
1. Turn off the ATD/TD and disconnect it from the line
supply.
2. Connect your external devices to the appropriate relay
contacts. Insert the wire leads into the connector and
tighten the screws.
3. Connect all of your devices.
4. Connect the instrument to AC power and turn it on.
Once all of the devices are connected, power them up and program
the timing for each device through the touch screen or through the
Control Software. Refer to Timing Tab on page 99 for details.
