Byte 2 is condition byte (see
).
4.7.67
Module 286 - CXS EXD Water Level
CXS water sensor in bottom of EXD enclosure.
Input Bytes:
Byte 1 is status. Values: 1 = Good, 0 = Bad (water leak)
Byte 2 is condition byte (see
).

).
4.7.70
Module 150 - CXS Spare
This signal is not normally used but provides a status signal to the control system.
Input Bytes:

Byte 2 is condition byte (see
).
4.7.71
Module 267 - CXS DP Body
This signal provides the status of the DP body thermal snapswitch.
Input Bytes:
Byte 1 is status. Values: 1 = Good, 0 = Bad
Byte 2 is condition byte (see
).
4.7.72
Module 289 - CXS Bypass Valve
CAUTION
Do not attempt to use this facility unless specific guidance and approval is provided by Edwards as under many
circumstances it may result in significant pump performance reduction and rapid pump life reduction.
This module provides Control of a CXS Bypass valve and feedback of its actual state. The valve is not used in most
applications but can be used either as a gate valve bypass (with a limited orifice for PID pressure control) or as a
partial exhaust gas recirculation valve for rapid pump heating. The later function has very considerable pump risk.
Output Bytes: Single byte is valve control. Values: 1=Open; 2=Closed; Other values - ignored.
Input Bytes:
Byte 1 is status. Values: 0=Off (Closed); 4= on (Open).
Byte 2 is condition byte (see
).
