HMIGTO的正面
安裝在實(shí)心面板中，已使用與規(guī)范中所示標(biāo)準(zhǔn)等效的條件進(jìn)行測試。盡管HMIGTO的阻力水平與這些標(biāo)準(zhǔn)相當(dāng)，但對(duì)HMIGTO沒有影響的油可能會(huì)損害面板。這可能發(fā)生在存在汽化油的區(qū)域，或允許低粘度切削油長時(shí)間粘附在面板上的區(qū)域。如果面板正面保護(hù)板脫落，這些情況可能導(dǎo)致油進(jìn)入面板，建議采取單獨(dú)的保護(hù)措施。此外，如果存在未經(jīng)批準(zhǔn)的機(jī)油，它們可能會(huì)導(dǎo)致前面板塑料罩變形或腐蝕。因此，在安裝HMIGTO之前，確保確認(rèn)面板操作環(huán)境中存在的條件類型。如果長期使用安裝墊片，或者從面板上拆下HMIGTO及其墊片，則無法保持原有的防護(hù)等級(jí)。為了保持原有的保護(hù)水平，請(qǐng)確保定期更換安裝墊片*2對(duì)于尺寸公差，所有+1/-0 mm（+0.04/-0 in）和R（角度）均低于R3（R0.12 in）*3即使安裝壁厚在“面板切割尺寸”的建議范圍內(nèi)，取決于壁的材料、尺寸和面板和其他設(shè)備的安裝位置，安裝壁也可能翹曲。為了防止翹曲，可能需要加強(qiáng)安裝表面。根據(jù)面板的工作溫度和使用年限，時(shí)鐘可以從-380秒/月偏離到+90秒/月。對(duì)于這種精度水平不足的系統(tǒng)，用戶應(yīng)進(jìn)行監(jiān)控，并在需要時(shí)進(jìn)行調(diào)整。
Specifications of Serial Interface COM2
Introduction NOTE: For information on how to connect controllers and other types of equipment, refer to the corresponding device driver manual of your screen editing software. The serial port is not isolated. The SG (signal ground) and FG (frame ground) terminals are connected inside the panel. Serial Interface COM2 HMIGTO2300 / HMIGTO2310 / HMIGTO2315: RJ45 connector via a RS-485 cable. NOTE: When setting up RS-485 communication, the cable diagram for some equipment may require polarization on the terminal side. This terminal does not require any special setting as it handles polarization automatically When using the SG terminal to connect an external device to the panel: ? Verify that a short-circuit loop is not created when you set up the system. ? Connect the #8 SG terminal to remote equipment when the host (PLC) unit is not isolated. Connect the #8 SG terminal to a known reliable ground connection to reduce the risk of damaging the circuit. Failure to follow these instructions will result in death or serious injury.For information on how to connect controllers and other types of equipment, refer to the corresponding device driver manual of your screen editing software.? All connections to the communication ports must not put excessive stress on the ports. ? Securely attach communication cables to the panel or cabinet. ? Use only D-Sub 9-pin cables with a locking system in good condition.
The front face of the HMIGTO
installed in a solid panel, has been tested using conditions equivalent to the standards shown in the specification. Even though the HMIGTO's level of resistance is equivalent to these standards, oils that should have no effect on the HMIGTO can possibly harm the panel. This can occur in areas where either vaporized oils are present, or where low viscosity cutting oils are allowed to adhere to the panel for long periods of time. If the panel's front face protection sheet peels off, these conditions can lead to the ingress of oil into the panel and separate protection measures are suggested. Also, if non-approved oils are present, they may cause deformation or corrosion of the front panel’s plastic cover. Therefore, prior to installing the HMIGTO, be sure to confirm the type of conditions that will be present in the panel’s operating environment. If the installation gasket is used for a long period of time, or if the HMIGTO and its gasket are removed from the panel, the original level of protection cannot be kept. To maintain the original protection level, be sure to replace the installation gasket regularly. *2 For dimensional tolerance, everything +1/-0 mm (+0.04/-0 in) and R in angle are below R3 (R0.12 in) *3 Even if the installation wall thickness is within the recommended range for the “Panel Cut Dimensions”, depending on wall’s material, size, and installation location of the panel and other devices, the installation wall could warp. To prevent warping, the installation surface may need to be strengthened.Depending on the operating temperature and age of panel, the clock can deviate from -380 to +90 sec/month. For systems where this level of precision is insufficient, the user should monitor and make adjustments when required.
