•辅助1、2、3操作：术语“故障安全”和“非故障安全”在PQM中定义如上。如果PQM因失去控制电源而无法运行时需要输出，则选择故障保护辅助操作，否则选择非故障保护。•辅助1、2、3激活：如果仅在所选条件存在时需要辅助继电器输出，请选择解锁。一旦选定条件消失，辅助继电器将返回非激活状态。为确保确认所有条件，请选择“已锁定”。如果条件不再存在，则可通过按键或通过计算机发送重置命令来重置辅助继电器。由于继电器可被分配执行许多不同的功能，PQM使用优先级系统来确定如果继电器被分配到多个功能，则哪个功能将控制继电器。下表显示了功能的优先级。
• AUXILIARY 1, 2, 3 OPERATION: The terms ‘failsafe’ and ‘non-failsafe’ are defined above as implemented in the PQM. If an output is required when the PQM is not operational due to a loss of control power, select failsafe auxiliary operation, otherwise, choose non-failsafe. • AUXILIARY 1, 2, 3 ACTIVATION: If an auxiliary relay output is required only while the selected conditions are present, select unlatched. Once the selected condition disappears, the auxiliary relay returns to the non-active state. To ensure all conditions are acknowledged, select latched. If the condition is no longer present, the auxiliary relay can be reset by pressing the key or by sending the reset command via the computer.Since the relays can be assigned to perform many different functions, the PQM uses a priority system to determine which function will control the relays if they happen to be assigned to more than one function. The Table below shows the priority of the functions.
