DD-100-B. This accessory allows all time delays to
be adjusted from 0 to 99 minutes.
Time Delay accessory DD-100-B increases all of the time
delays up to 99 minutes. The time delays are used for
transfer from normal to emergency, transfer from
emergency to normal, engine start, engine cooldown,
and load-shed sequence. The TIME DELAY jumper
must be installed on the main logic board to increase the
adjustable range of standard time delays up to
99 minutes. See Figure 4-15. To extend TDES time
delays an external 12-32 vdc power supply is required.
