1. The timers may be set using SW2-1 to SW2-5. This method is invoked by switching SW2-
7 on. This method is recommended when all timers have the same time setting.
2. Programming the memory of the Omni30 using the optional Software Configuration Utility
will set each input timer individually. If this memory is not programmed, then the timers
default to the switch settings. This method should be used when different input timer
settings are required.

Slow = Uses the Slow timer i.e. 1 sec increments
Fast = Uses the Fast timer i.e. 1/10 sec increments
Example:
SW1-8 must be off to enable SW2

4.6.1 Omni30 Fast and Slow Timers
Figure 4-1 above shows the use of the Fast and Slow timer. These timers allow the
user the most flexible timing options. For very short timing durations, the Fast timer
should be used. This timer counts time in units of 100ms or 1/10 of seconds.
For longer time periods, the Slow timer should be used. This timer is derived from the
Fast timer and therefore counts time in multiples of the Fast timer. The default setting of
the Slow timer is to count time in seconds. It is possible to alter the timing mechanism
of the Slow timer to count in larger units of time via the programming port.
4.6.2 Explanation of Timer Operation in a Timer Sequence
With reference to any one of the special timer sequences:
When the alarm point moves from a state where the timer is stopped to a state where
the timer is running, the timer will be started.
When the alarm point moves from a state where the timer is running to a state where
the timer is also running, the timer is allowed to continue timing.
When an alarm point moves from a state where the timer is running to a state where
the timer is stopped, the timer is put into the timed-out (stopped) state.
4.7 Selecting Serial Port Settings
The Omni30 can be equipped with an optional RS232/485 serial port. This port supports the
Modbus protocol. In Switch set mode, inputs and outputs can be read via the serial port using
