发电机过压-硬件关闭。启用硬件关机将导致DECS-100：超过发电机过电压设置时，消除励磁。禁用硬件停机可防止DECS-100在发电机过电压条件下消除励磁。发电机过压——报警。此设置启用和禁用DECS-100报警输出的关闭（端子AL1和AL2）。禁用报警也会禁用硬件关机。
现场过电压-电压电平（Vdc）。该字段中的值可在0到250 Vdc之间调整，并且确定将导致DECS-100发出过励磁极限报警的磁场电压水平。
当磁场电压增加超过该磁场值10秒时，过励磁关闭前面板灯上的LED。
现场过电压-报警。如果警报被启用并且场过电压条件存在10秒，DECS-100报警输出（端子AL1、AL2）将关闭。禁用报警可防止报警存在磁场过电压条件时闭合输出。禁用报警也会禁用硬件关机。
现场过电压-硬件关闭。当硬件关闭启用时，DECS-100将当磁场过电压条件存在10秒时，消除磁场激励。
传感电压损失-LOS选项。可以选择两个DECS-100响应中的一个，以减少感测电压状况。
选择停机调节器将导致DECS-100移除磁场
发生感测电压损失时的激励。选择转移到FCR将导致DECS-100：发生感测电压损失时，转换到FCR模式。
感测电压损失-时间延迟（秒）。该字段的值决定了当识别到感测电压损失时，DECS-100根据硬件做出响应选择关机和LOS选项。可以在1秒内输入0到25秒的时间延迟增量。
感测电压丢失-硬件关闭。启用硬件关机将导致DECS-100以在发生感测电压损失时消除场激励。禁用硬件关机可防止DECS-100在感测电压损失期间消除激励。
限位片限制器选项卡设置如图5-15所示，并在以下段落中描述。
OEL——电流水平（A）。该字段中的电流值决定将导致的励磁水平DECS-100发出过励磁极限报警。0.01中可输入0至15 A的电流水平增量。当磁场电流水平增加超过该磁场值时，过励磁关闭前面板上的LED灯，OEL时间延迟开始计时。
Generator Overvoltage - Hardware Shutdown. Enabling Hardware Shutdown will cause the DECS-100 to
remove field excitation when the generator overvoltage setting is exceeded. Disabling Hardware
Shutdown prevents the DECS-100 from removing excitation during a generator overvoltage condition.
Generator Overvoltage – Alarm. This setting enables and disables closure of the DECS-100 Alarm output
(terminals AL1 and AL2) during generator overvoltage. Disabling the alarm also disables hardware
shutdown.
Field Overvoltage - Voltage Level (Vdc). The value in this field is adjustable from 0 to 250 Vdc and
determines the field voltage level that will cause the DECS-100 to issue an overexcitation limit alarm.
When the field voltage increases above the value of this field for 10 seconds, the Overexcitation
Shutdown LED on the front panel lights.
Field Overvoltage - Alarm. If the Alarm is enabled and a field overvoltage condition exists for 10 seconds,
the DECS-100 Alarm output (terminals AL1, AL2) will close. Disabling the Alarm prevents the Alarm
output from closing when a field overvoltage condition exists. Disabling the alarm also disables hardware
shutdown.
Field Overvoltage - Hardware Shutdown. When Hardware Shutdown is enabled, the DECS-100 will
remove field excitation when a field overvoltage condition exists for 10 seconds.
Loss of Sensing Voltage - LOS Option. One of two DECS-100 responses can be selected for a loss of
sensing voltage condition. Selecting Shutdown Regulator will cause the DECS-100 to remove field
excitation when loss of sensing voltage occurs. Selecting Transfer To FCR will cause the DECS-100 to
transfer to FCR mode when a loss of sensing voltage occurs.
Loss of Sensing Voltage - Time Delay (sec). The value of this field determines the time delay between
when a loss of sensing voltage is recognized and the DECS-100 responds according to the Hardware
Shutdown and LOS Option options selected. A time delay of 0 to 25 seconds may be entered in 1 second
increments.
Loss of Sensing Voltage - Hardware Shutdown. Enabling Hardware Shutdown will cause the DECS-100
to remove field excitation when a loss of sensing voltage occurs. Disabling Hardware Shutdown prevents
the DECS-100 from removing excitation during a loss of sensing voltage.
Limiter Tab
Limiter tab settings are shown in Figure 5-15 and described in the following paragraphs.
OEL - Current Level (A). The value of current in this field determines the excitation level that will cause
the DECS-100 to issue an overexcitation limit alarm. A current level of 0 to 15 A may be entered in 0.01
increments. When the level of field current increases above the value of this field, the Overexcitation
Shutdown LED on the front panel lights and the OEL time delay starts timing down.
