發電機過壓-硬件關閉。啟用硬件關機將導致DECS-100：超過發電機過電壓設置時，消除勵磁。禁用硬件停機可防止DECS-100在發電機過電壓條件下消除勵磁。發電機過壓——報警。此設置啟用和禁用DECS-100報警輸出的關閉（端子AL1和AL2）。禁用報警也會禁用硬件關機。
現場過電壓-電壓電平（Vdc）。該字段中的值可在0到250 Vdc之間調整，并且確定將導致DECS-100發出過勵磁極限報警的磁場電壓水平。
當磁場電壓增加超過該磁場值10秒時，過勵磁關閉前面板燈上的LED。
現場過電壓-報警。如果警報被啟用并且場過電壓條件存在10秒，DECS-100報警輸出（端子AL1、AL2）將關閉。禁用報警可防止報警存在磁場過電壓條件時閉合輸出。禁用報警也會禁用硬件關機。
現場過電壓-硬件關閉。當硬件關閉啟用時，DECS-100將當磁場過電壓條件存在10秒時，消除磁場激勵。
傳感電壓損失-LOS選項。可以選擇兩個DECS-100響應中的一個，以減少感測電壓狀況。
選擇停機調節器將導致DECS-100移除磁場
發生感測電壓損失時的激勵。選擇轉移到FCR將導致DECS-100：發生感測電壓損失時，轉換到FCR模式。
感測電壓損失-時間延遲（秒）。該字段的值決定了當識別到感測電壓損失時，DECS-100根據硬件做出響應選擇關機和LOS選項。可以在1秒內輸入0到25秒的時間延遲增量。
感測電壓丟失-硬件關閉。啟用硬件關機將導致DECS-100以在發生感測電壓損失時消除場激勵。禁用硬件關機可防止DECS-100在感測電壓損失期間消除激勵。
限位片限制器選項卡設置如圖5-15所示，并在以下段落中描述。
OEL——電流水平（A）。該字段中的電流值決定將導致的勵磁水平DECS-100發出過勵磁極限報警。0.01中可輸入0至15 A的電流水平增量。當磁場電流水平增加超過該磁場值時，過勵磁關閉前面板上的LED燈，OEL時間延遲開始計時。
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.
