For equipment to be used by the general public, please contact the factory.The Star-Max Electric Hot Plates are equipped for the voltage indicated on the nameplate mounted on the front panel. This unit is designed to operate on alternating current (A.C.), two wire single phase service only.DO NOT CONNECT TO DIRECT CURRENT (D.C.).Total Connected Load:501FF: at 240 Volts, Wattage is 2,600.at 208 Volts, Wattage is 1,950.502FF: at 240 Volts, Wattage is 5,200.at 208 Volts, Wattage is 3,900.For your protection, we recommend that a qualified electrician install this appliance. The electrician should be familiar with electrical installations and your local electrical requirements. The externalwiring should be in conduit or an approved type of flexible cable and of suitable size to carry the load. The supply circuit should be properly fused and equipped with a means of disconnecting as required by local electrical code. The body of the hot plate should be grounded (Do not ground to a gas supply pipe). The connections are made in this unit at the pigtail leads located in the junction box on the back of the unit. To gain access to the pigtail leads remove cover on junction box.LOCATE THE UNIT Do not install the unit closer than 1 inch from a side wall and/or closer than 1 inch from a rear wall.LEVELING UNITLevel unit by adjusting the (4) feet for accurate and perfect line up with other Star-Max series units.DO NOT INSTALL WITHOUT FEET.USE ONLY FLAT BOTTOM PANS AND POTS! DO NOT USE RAISED BOTTOM UTENSILS OR BUCKETS! GOOD HEAT TRANSFER DEPENDS UPON GOOD CONTACT BETWEEN THE ELEMENT AND POT.NOTE: Using a 12” diameter or larger pan/pot may cause damage to the element or internal wiring. Such damages are not covered by warranty.Two (2) heating elements are used. For the 501FF and 502FF each element draws 2,600 Watts on 240 Volts and 1,950 Watts on 208 Volts. Each element is controlled by an infinite position switch. The right control knob controls the rear cooking element and the left control knob controls the front cooking element for the 502FF. On “HI” the element delivers uninterrupted full heat. Between “LO” and “5” any desired amount of heat can be obtained between 6% and 60% of full heat.Signal lights are provided above the control knobs to give a visual check of the corresponding heating element per each knob.CAUTIONCAUTIONCAUTIONWARNINGCAUTIONAppliances must be disconnected from power supply during cleaning, or maintenance and whenreplacing parts. The exterior surfaces can be kept clean and attractive by regularly wiping with a clean WARNINGsoft cloth. Any discoloration can be removed with a non-abrasive cleaner. When appliance is installedin a bank of other appliances, it shall not be cleaned with a water jet or a steam cleaner.BE SURE POWER IS DISCONNECTED BEFORE ATTEMPTING TO SERVICE UNIT.1. Pull control knobs on front panel forward to remove.2. Remove 8 screws from front panel and tilt front panel forwards.3.

图5.1：8080 (4/8-bit) MPU 与LCM的界面图图5.2是8080系列MPU与LCM间的系统时序图，在LCM的定义中，RS 为 “L” 时，是表示对缓存器下命令，也就是对LCM的缓存器进行读写的动作(Register Access Cycle)，而RS 为 “H” 时是表示对Display RAM 进行Data 读写的动作(Data Access Cycle)。
不论是8080 或6800， “RS” Pin 通常接到MPU 的Address Pin “A0”，8080 系列MPU 与6800 最大的不同是Read、Write 的控制信号是分开的，RD 为Low 时是进行读取动作，WR 为Low 时是进行写入动作，至于读写的目的地则由RS 决定。
下图5.2表示如果是对缓存器进行读取动作，MPU 必须透过数据总线先送出缓存器的地址，然后才能在数据总线上读取缓存器的数据，如果是对缓存器进行写入动作，MPU 必须透过数据总线先送出缓存器的地址，然后再送出要写入的数据。
当8088 MPU 对LCM Display RAM 进行数据的读取动作，MPU 能直接在数据总线上读取Display RAM 的数据，如果8088 MPU 对Display RAM 进行数据的写入动作，MPU 则直接在数据总线上送出要写入的数据。
图5.2：8-Bit 8080 MCU 对LCM缓存器/DATA 进行读取/写入动作第 3 页，共 84 页2、6800系列MPU说明：图5.3 是LCM 与6800 兼容系列的MPU 接口示意图，此时LCM 将只接受6800 系列兼容的MPU 所传送出来的控制时序。
图5.3：6800 (8-bit) MPU 与LCM的界面图6800 系列MPU Read、Write 的控制信号是同一根Pin，R/W 为High 时是进行读取动作，R/W 为Low 时是进行写入动作，而EN 则是确定读写的动作是否有效(Enable)，至于读写的目的地仍由RS 决定。
此LCM无法同时接受6800 及8080 的控制信号，因此在MPU 的接口上，某些脚位上会因为使用者选择不同的MPU 而有不同的定义，例如脚位/RD(EN)，当使用者选择的MPU 接口为8080 时是定义成/RD，而选择6800 MPU 时是定义为EN。
而脚位/WR(R/W)，当使用者选择的MPU 接口为8080时是定义成/WR，而选择6800 MPU 时是定义为R/W。
下面图5.4表示如果是6800 MPU 对LCM缓存器进行读取动作，MPU 必须透过数据总线先送出缓存器的地址，然后才能在数据总线上读取缓存器的数据，如果是对缓存器进行写入动作，MPU 必须透过数据总线先送出缓存器的地址，然后再送出要写入的数据。
当6800 对LCM Display RAM进行数据的读取动作，MPU 能直接在数据第 4 页，共 84 页第 5 页，共 84 页总线上读取Display RAM 的数据，如果6800 MPU 对Display RAM 进行数据的写入动作，则MPU 直接在数据总线上送出要写入的数据。
对于6800 MPU 的接口，LCM只提供8Bit 的传输功能，而对于8080 MPU 的接口，LCM 提供4Bit 或8Bit 的传输功能。
图5.4：8-bit 6800 MPU 对LCM 缓存器/Data 进行读取/写入动作3、4Bit/8Bit 的MPU 接口：此中文字库液晶显示模块除了支持8080 和6800 两大系列兼容的MPU 接口外，也可以设定MPU 上的数据总线接口是4-Bit 或是8-Bit，出厂时默认8-Bit 接口。
因为控制IC 内部的缓存器大多是8-Bit 的架构，因此如果使用4-Bit 的数据总线接口，MCPU 将会花较多的周期(Cycle)去存取内部的缓存器。
当选择4-bit MCU 作传输模式时，中文字库液晶显示模块的MCU 接口只有用到数据总线的DB3～DB0，而没有用到的DB7～DB4 则不必理会(当成NC Pin)，同时每一个八位的指令或资料将被分为两个Nibble (4-Bit) 依序透过数据总线的DB3～DB0 进行传送，第一次先透过总线(DB3～DB0) 传送资料的较高位Bit[7..4]，第二次再透过总线(DB3～DB0)传送资料的较低位Bit[3..0]。
六、中文字型ROM：此中文字库液晶显示模块内建有512KByte 的16×16 中文显示字型ROM(Font ROM) 与8×16 的ASCII 半型字型。
除了内建的8×16 和16×16 的字号外，还提供字型放大的功能，可利用REG[F1h]的设定，将显示字号放大到32×32、48×48 或64×64。
控制IC 分带繁体字库IC 和带简体字库IC，其中标准繁体中文BIG5 码，包含13,094 个常用与次常用字型、408 个特殊字与两组ASCII CODE；简体字库储存7602 个标准GB 码的简体中文。
缓存器[F0h]是用来设定与字型ROM 相关的功能，当使用带繁体字库IC 时，必须将Bit[5..4]设成“01” 才能正确显示繁体字型，当使用带简体字库IC 时，必须将Bit[5..4]设成“10” 才能正确显示简体字型。
注意：中文内码不论是GB 或BIG5 码都是由两个Byte 组成，但是英文及一些符号ASCII 码只由一个Byte 组成(00h～FFh)，通常LCM 将送到Display RAM 的Data(00h～9Fh)视为ASCII码，也就半角文字(8×16)，大于等于 “A0h”的视为全角码(如繁简中文)的高位，必须再送一次低位内码，才能显示全角字型。
如果使用者有用到A0h～FFh 的ASCII 码，则MPU 在送Data(ASCII 码)到Display RAM 之前必须将缓存器[F0h]的Bit2 设成 “1” 。
