GST104 Conventional Fire Panel (hereinafter called GST104 panel)can monitor 4 zones. GST102 Conventional Fire Panel (hereinafter called GST102panel) can monitor 2 zones. Those with signal output interface board has a passivenormally open alarm output contact and fault output contact for each zone. Each zonecan be connected with 15 conventional fire detectors. They have two external controloutput points to control some devices such as sounder strobe and sounder etc. Thestated maximum load is two sounder outputs. They are designed with internal standbybatteries and space for installation (two sealed acid storage batteries). They havefunctions of test and isolation, setting day/night mode, indication of normal state, faultstate, alarm state, alarm of short circuit and open circuit of external connections andidentifying the location of the detecting zone. The installation and operation of the twokinds of panel are very simple and convenient. All the control functions can be realizedthrough a key switch, and the programming function can be realized through a keyswitch and an internal switch. Except for two monitoring zones (two zone input) less, two passive normally open alarmoutput contacts and two passive normally open fault output contacts less for those withsignal output interface board, and some minor differences in appearance and structure,GST102 panel is the same as GST104 panel in technical specifications, usage andoperation.

If daymode is selected, "DAY MODE" LED is lit. 4) Note: If the panel works in day mode for over 18 hours, it will change to night modeautomatically. At the same time, the "DAY MODE" LED flashes. The panel turns into fault. At level 2, press “Reset” to clear the fault. 4.1.3 Self-check and Fire Alarm Clearance1) Self-check and fire alarm clearance is in operation level 2.2) Press “Reset” for 1 second to clear fire alarm in alarm state, to self-check the soundand LEDs in other states and to clear test and fault state. 4.1.4 Control of External Sounders1) As in Fig. 4.1.4.1, when the “Evacuate” lock points to “I”, the 2-channel externalsounder is activated.Fig. 4.1.4 .12) As in Fig. 4.1.4.2, when the “Evacuate” lock points to “O”, the external sounder4.2 Setting of Isolation State1) Isolation state setting is valid for the four detecting zones.2) Rotate the “CONTROL ENABLE” lock to “I”, press “Select” key for 1 second, the“Isolate” LED flashes; Press “Enter”, the “Isolate” LED becomes constantly lit and enters isolation setting state (see Fig. 4.2a – 4.2d).Fig. 4.1.4.2Select Enter3) Press “Select” to select one zone, press “Shift” to change the isolation state of theselected zone. The isolation state is indicated by the "Fault" LED of the corresponding zone, which is off in normal state and constantly lit in isolation state. The “Fire” LED of the corresponding zone, which flashes when selected, indicates th zone (Fig. 4.2e and 4.2f).Fig. 4.2eSelect Fig. 4.2d4) Press “Enter” to exit and save the setting (see Fig. 4.2g).Day/Night Fig. 4.2f EnterFig. 4.2gReset Fig. 4.2h4.3 Setting of Test State It is set in operation level 2.1) Press “Select” key for 1 second, “Isolate” LED flashes.

综合保护装置在煤矿井下皮带机中的运用摘要：煤矿井下带输送机在使用的过程中担负着运输煤炭的重要工作任务，输送机电控系统自动化水平深刻影响煤矿的运行发展。
文章以KTC102型带式输送机综合保护装置为基本研究对象，就综合保护装置在煤矿井下的应用原理、系统组织、安装操作等问题进行探究。
关键词：KTC102型带式输送机综合保护装置；煤矿井下皮带机；应用当前，皮带机综合保护装置逐渐成为矿井下皮带运输中最常用的保护，在使用的过程中具有极高的可靠性和性价比、强大的通讯能力、液晶屏汉字显示、丰富的操作及功能按键、语音报警等特点，被人们广泛应用到煤矿开采中，是一种适合应用到煤矿井下特殊环境中的智能化装置。
但是从实际应用情况来看，综合保护装置在煤矿井下皮带机中的实际运用过程中由于安装不到位出现了安全事故，如输送带断裂与撕裂、制动失灵、摩擦起火等。
为了确保综合保护装置在煤矿井下皮带机中的有效应用，需要相关人员加强对综合保护装置原理、系统协调、传感器安装的正确掌握。
一、煤矿井下皮带机综合保护装置原理煤矿井下皮带机综合保护装置是一种矿用防爆产品，能够实现对煤矿井下带式输送机电气控制系统的综合保护。
在社会科技的发展下，煤矿井下皮带机综合保护装置的智能化水平、安装操作功效等相应的提升，在使用的过程中能够适应固定式或者伸缩式的输送机启动操作，在复杂、多样的环境下也能够得到有效应用。
另外，煤矿井下皮带机综合保护装置在实现单机控制的基础上还能够通过数据信息的传输、组网系统来实现无人值守，提升煤矿安全生产及信息化水平。
KTC102型带式输送机综合保护装置供电电压AC 127V （波动范围－15％～＋15％），在使用中具有输入、输出、语音通讯、安全保障、自诊断等功能。
全系统按本质安全性能设计（电源除外），适合煤矿井下使用。
煤矿井下皮带机综合保护装置的控制方式分为手动操作、自动操作、遥控操作三种。
其中，手动操作控制的实现需要借助转换开关的接点控制系统，在手动操作控制下能够将煤矿井下皮带机的信号检测信息、信号应用显示信息进行反应。

b.系统自动复位当系统正常工作后，主处理器经过D4-37脚不断发出一种固定频率的脉冲,经C9隔直,D14整形,输入D13-12,D13为一个方波发生器,只有D13-12脚不断接收到脉冲信号,D13才不会起振,否则,D13起振,延时一段时间后,D13-14脚输出一个复位高脉冲,经V36将复位信号送到CPU上,从而在复位端上实现了自动复位过程。
如果上电后，系统处于返复上电状态，这时很可能是看门狗电路故障，检修可用示波器，采用倒推法，见图2-3图2-3 检修流程■输出部分设备的启停在控制板上即为继电器的通断。
现在给出其中一个继电器的动作原理图2-4，其它继电器原理依此类推。
图2-4当D4-10脚置高，同时D4-13、17置低时D5-7脚置低，光耦合D18导通，继电器J1动作，设备起动。
这里要保证D5-1、15同时置低，这就是本系统中双重反驱动，以保证全系统能正常可靠运行。
■输入部分输入电路原理图见图2-5图2-5 输入电路原理图如图所示，当外电路的开关K闭合后D16导通，D4的18脚置低，从而实现了输入信号的检测。
■急停闭锁部分：为了保证系统在紧急情况下，按下闭锁按钮，绝对停车，系统在控制继电器回路中加入强制闭锁（注意：只有其中的六路，另外六路直接接地）图2-6 闭锁控制继电器电路图从上图可以看出，要保证继电器吸合，首先由CPU发出启车指令使D*导通，将正12V加到继电器正端。
同时M1，M2导通，使继电器接地，形成通路。
M1，M2点受D33、D34控制，D33、D34检测电路为强制闭锁检测电路。
不管是CPU发出停车信号还是将M1、M2任何一个断开都能将继电器断电，从而实现了双重闭锁功能。
D33为直流检测，D34为“交流”检测，所谓“交流”，实际是在某一直流电压上的脉动，它由终端发出经闭锁线传递到控制器的主控板上（见图8中所示的15点），见波形图2-7图2-7 脉动电路波形图控制板上的指示灯∶红色5V指示（5V电源由9V电源模块提供）绿色18V指示系统能否正常工作，5V是很重要的，在检修控制板时应检测5V电源是否在4.6~5.5V之间,一般低于4.6V系统不能稳定工作,高于5.5V系统将被烧坏。
1.2 接线端子排KTC102控制程序种类繁多，接线方式及控制点位置要根据程序要求来选择。
下面只列举两种常用程序的接线表（见图2-8、图2-9）。
图2-8 图2-91.3 键盘部分键盘电路原理图见图2-10图2-10键盘执行过程：在没有按下按键时，D9-1脚输出高电平“1”，当按下任意键时，D9-1脚由“1”变“0”单片机读入数据，因此，这二种状态是辨别键盘好坏的重要标志。
配合检查其它输入点电平的变化，就可以判断键盘是否能正常工作。
显示部分：在控制板上有一只10K电位器,通过它可以调节显示辉度,液晶显示文字的深浅,电路原理图见图2-11图2-11 显示部分辉度调整原理图1.4 语音处理模块：语音处理模块在工作时由内置电池供电，外电路电源只需给语音模块电池提供一定量的充电电流即可。
供电电压为：14~18V 充电电流：15~30mA分四档可调输出功率：5W 输出阻抗：8图2-12 图2-13语音处理模块外围电路介绍■开关接插件X3（从右到左）1# 放音电路电源正，通过开关K4常闭点同（7#）电池正极相连接。

■充电电流调整：通过调整两位的微动开关K，可以调整充电电流的大小，使充电电流在15、20、25和30mA四档可调。
调整方法参见图15■送话音量调整：W1为送话音量调整电位器，W2为放音音量调整电位器，一般顺时针方向旋转电位器可增大音量。
1.5 语言报警板：分工作面报警程序和皮带报警程序两种，报警音量可调。
1.6 送话小开关组件：送话小开关分为两种结构：双组单刀双掷微动小开关（图2-14）单组双刀双掷钮子开关（图2-15）图2-14 图2-15 送话小开关组件原理图（参见图2-12中的K3、K4部分）。
