2. START/STOP CONTROL AND COMMAND
Start/Stop registers are polled by the controller every 250mS.
40098 System Disable 0x5DA2 (23970) W When 0x5DA2 is written to address 40098 this
places the controller in the OFF mode (System
disabled). The register is read in all control-
ler operating modes (Running, Auto, Failure,
Menu/sleep modes).
CAUTION – when
received in the Running mode the control-
ler immediately goes to the OFF mode (no
cool-down is performed). When received in
failure mode this will reset the system failure
and revert to the OFF mode.
System Enable 0x5BA4 (23460) W When 0x5BA4 is written to address 40098 this
places the controller in the AUTO mode (wait-
ing to start).
The register is read only in the
OFF mode of operation and ignored in all
other operating modes.
Stop 0x57A8 (22440) W When 0x57A8 is written to address 40098
this initiates a shutdown/stop of the equip-
ment. This register is only monitored when the
system is running (start signal received) and
is ignored in all other operating modes.
When
cool down is enabled and a stop command
is received the controller will proceed to the
cool down mode then shutdown equipment.
