項目規(guī)劃/維護說明/附加信息
? 在調(diào)試放大器之前，必須確保設(shè)置了印刷電路板上的DIL開關(guān)根據(jù)相關(guān)應(yīng)用。
? 在所提供的條件下，參數(shù)設(shè)置如下（參數(shù)設(shè)置參見第8至10頁）：最大斜坡時間=5秒，導(dǎo)頻電流=100 mA，最大輸出電流=800 mA，時鐘頻率=200 Hz。
? 放大器卡只能在斷電時組裝。
? 電磁閥連接不得使用帶續(xù)流二極管或LED顯示器的接頭。
? 只能使用Ri>100 kΩ的儀器在板卡上進行測量。
? 測量零點（M0）與0 V工作電壓相比增加+9 V，且未隔離，即-9 V調(diào)節(jié)電壓? 0V工作電壓。因此，不要將測量零點（M0）連接到0V工作電壓。
? 對于開關(guān)指令值，必須使用帶有鍍金觸點的繼電器（低電壓、低電流）。
? 始終屏蔽命令值線，在板卡一側(cè)將屏蔽接地，另一側(cè)打開?？ū仨毷峭ㄟ^端子6或8接地。如果不存在系統(tǒng)接地，則連接0 V工作電壓。
? 建議：同時屏蔽電磁線圈導(dǎo)體。對于長度不超過50 m的螺線管導(dǎo)線，應(yīng)使用LiYCY 1.5 mm2線型。如需更多長度，請聯(lián)系我們。
? 與架空線路、無線電和雷達系統(tǒng)的距離必須至少為1米。
? 不要將電磁線圈導(dǎo)線和信號線放置在電源線附近。
? 板卡上平滑電容器的充電功率要求預(yù)熔絲具有緩慢熔斷特性。
? 通知：
如果使用差分輸入，則必須始終同時連接或斷開兩個輸入。故障排除
如果放大器卡不工作，請執(zhí)行以下步驟
故障排除需要：
1.工作電壓是否可用？觸點24（交流）對18（交流）的測量
2.卡上的保險絲有故障嗎？
3.板卡上是否有內(nèi)部±9 V工作電壓？
4.如果使用內(nèi)部命令值電位計，
10（交流）至12（交流）之間的電橋是否可用？
5.外部電位計是否正確連接？
6.差分輸入是否正確連接？
控制：參考電位為30（交流）0至+10 V至28（交流）
7.電磁閥是否正確連接？
如果拔下板卡，電阻約為20Ω至30? 或5Ω至8Ω必須在觸點22ac和20ac取決于閥類型。
括號中連接名稱的修改僅適用于VT-VSPA1-1型。
通知：輸出級在超溫時關(guān)閉（例如，由于過載）。該錯誤由“H2”指示燈熄滅。
如果輸入“4至20 mA”的電纜斷開，“準備“操作”信號復(fù)位，“H2”LED將熄滅，
也以下適用于組件系列11：如果電磁線圈導(dǎo)體短路或電纜斷裂，則“準備運行”輸出將計時，并且“H2”LED將以0.5至2 Hz的頻率快速閃爍因為指令值同時大于2%。
Project planning/maintenance instructions/additional information
? It has to be ensured before commissioning of the amplifi ers that the DIL switches on the printed circuit board are set
according to the relevant application.
? In the condition as supplied the parameters are set as follows (for the parameter setting refer to pages 8 to 10):
Max. ramp time = 5 s, pilot current = 100 mA, max. output current = 800 mA, clock frequency = 200 Hz.
? The amplifi er card may only be assembled when de-energized.
? No connectors with free-wheeling diodes or LED displays must be used for solenoid connection.
? Only carry out measurements at the card using instruments Ri > 100 kΩ.
? Measurement zero (M0) is increased by +9 V compared to 0 V operating voltage and not isolated, i.e. –9 V regulated
voltage ? 0 V operating voltage. Thus, do not connect measurement zero (M0) to 0 V operating voltage.
? For switching command values, relays with gold-plated contacts have to be used (low voltages, low currents).
? Always shield command value lines, connect shielding to earth on the card-side, other side open. The card has to be
connected to the earth via terminal 6 or 8. If no system earth exists, connect 0 V operating voltage.
? Recommendation:
Also shield the solenoid conductor. For solenoid conductors up to 50 m in length, use the line type LiYCY 1.5 mm2.
For greater lengths, please contact us.
? The distance to aerial lines, radios, and radar systems has to be 1 m at least.
? Do not lay solenoid conductors and signal lines near power lines.
? The charging power of the smoothing capacitor on the card requires the pre-fuses to be of a slow-blowing nature.
? Notice:
If the diff erential input is used, both inputs must always be connected or disconnected at the same time. Troubleshooting
If the amplifier cards do not function, the following steps
are required for troubleshooting:
1. Operating voltage available?
Measurement of contacts 24(ac) against 18(ac)
2. Fuse on the card faulty?
3. Internal ±9 V operating voltage available on the card?
4. If the internal command value potentiometers are used,
is the bridge from 10(ac) to 12(ac) available?
5. Is the external potentiometer correctly connected?
6. Is the differential input correctly connected?
Control: Reference potential to 30(ac)
0 to +10 V to 28(ac)
7. Is the solenoid correctly connected?
If the card is removed, a resistance of approx. 20 Ω
to 30 ? or 5 Ω to 8 Ω has to be measurable between
contacts 22ac and 20ac depending on the valve type.
The amendment of the connection designations in brackets
only applies to type VT-VSPA1-1.
Notice:
The output stage switches off at overtemperature
(e.g. due to overload). This error is displayed by the
"H2" LED going out.
In case of cable break of input "4 to 20 mA", the "ready for
operation" signal is reset and the "H2" LED will go out,
as well.
The following applies from component series 11:
In case of short-circuit or cable break of the solenoid conductor, the ready for operation output will clock and the
"H2" LED will flash with a frequency of 0.5 to 2 Hz as soon
as the command value is simultaneously > 2 %.
