PROGRAMMING THE DIALER SYSTEM

For this section, the key stroke entries are CAPITALIZED. The system’s response,
whether visual or audible, are enclosed within [BRACKETS].

The system must be in the Halt mode [Red run light] to accept programming
information. If it is not in the Halt mode, depress the HALT key to force that condition.

A. FAULT MODE PROGRAMMING

The fault status of each of the five channels is shown as a fault (RED) or no-fault
(GREEN) condition on the corresponding front panel indicator. The system allows the
user to specify whether an open contact condition should be regarded as a no-fault
(GREEN), or as a fault (RED) state. To program each channel, first apply a known fault
contact state to each input. This means shorting the input if a normally closed contact
mode is to be used, or opening the input connections if a normally open contact mode is
to be used. The 250 Real Voice system allows you to train the input for the proper
mode choice.

For each fault input channel, perform the following programming steps:

1.

ENTER, MODE, No.(1,2,3, or 4)

[indicator No. will flash, verifying selection]


2.

The selected indicator will alternate between RED and GREEN at one second
intervals. When the indicator for the channel being programmed is in the
proper state (RED or GREEN) for the applied input, depressing ENTER again
will select that mode.


To verify the proper mode, simulate the opening or closing of the fault input contacts
and view the proper state indication (RED or GREEN) on the system front panel.


B.

FAULT DELAY TIME PROGRAMMING


Each channel may be programmed for its own fault delay time response, from 1 to 99
seconds. This means that the system will neither display or respond to a fault channel
changing from a no-fault to a fault condition for this time period. Changes from a fault to
a no-fault condition are, however, instantly detected by the system.

The 250 Real Voice system allows the user to train the fault detection sequence to set
the desired fault detection delay.
