INT/EXT/CONT STORE
This three -way split-field indicator lights red in an individual field when an error is
detected. Pressing this switch or executing the error option of the microprogram should
reset the error and turn off the indicator field. H the error persists, notify the Honeywell
field service engineer.
OPERATOR INTERRUPT
Pressing this switch lights the indicator white and causes the information stored in the
ADDRESS/SIMUL.\ TE switches to be sent to the EUS as status for a special interrupt. The
operator interrupt state is reset by the microprogram and the indicator goes out automatically.
HALTED
This indicator lights blue when the DSC goes into the halt state.
INITIALIZE
Pressing this switch lights the HALTED indicator and resets the DSC to the initialized
state. The indicator lights white.
ADDRESS/SIMULA TE
These four thurnbwheel switches are used in conjunction with the OPERATOR INTERRUPT
switch to permit· the user to address various functions of the DSC. The desired setting
depends upon the specific application required. In conjunction with the maintenance panel
these switches are used for diagnosing the DSC. Care should be taken not to change these
switches while they are being sensed by the microprogram, since an error could result.
Control Configuration Switches
These switches consist of 16 MICROPROGRAM READABLE switches, 0-15 (see
Figure 3 -3). The switches for the freestanding model are located behind the swing-down
panel of the operator panel; those of the model integrated in the ICU are located on the
'maintenance panel behind the ICU right front narrow door. The switches are set by the
Honeywell field engineer for proper operation of the subsystem and should not be disturbed
by the operator.
The only switches the operator may need to use in case of subsystem
reconfiguration are switches 2, 8, 9 and 10 (see Table 3-1).
