●管路设计要求避免停机后形成气囊和油流回压缩机（安装油冷与压缩机水平或低于压缩机）。
●由于增加了油回路的容积（油冷，冷却管路），可 能需要在油管路上安装一个电磁阀以避免停机后 油回流至压缩机。
该电磁阀应离压缩机的回油口 尽可能的近，同时电磁阀的通断应与主接触器的 常开触点保持同步。
建议安装如下额外附件： － 视油镜，监测油流。
－ 手动球阀，在进出口安装以便维护。
－ 油过滤器（最大网孔尺寸25μm ），在油冷 位置较远或部件清洁度不能保证时使用。
若额外注油量不超过压缩机标准注油量的10%， 同时能够保证冷却回路各组件清洁度，则上述额 外措施可以省略。
其它非标设计均需单独审核。
●油冷必需有油温控制（温度设定见下表）●Install oil cooler as close as possible to the compressor.●Piping design must avoid gas pads and any drainageof oil into the compressor during standstill (install the oil cooler preferably at compressor level or below).●Due to the additional oil volume (cooler, piping) a solenoid valve may be necessary in the oil line. This is to avoid oil migration into the compressor during standstill. The solenoid valve must be installed close to the compressor’s oilinlet connection and it’s electric cont- rol should be parallel to the contactor’s normally open contact. Recommended additional components: - sight glass to monitor oil fl ow,- manual shut-off ball valves in both feed and return lines for ease of service,- oil fi lter (max. 25 μm mesh size) in case of remote oil cooler or if cleanliness of components is not guaranteed.Up to an additional oil volume (cooler and piping) of 10% of the compressor’s standard oil charge and as- sured cleanliness of components and pipes the above mentioned additional measures can be omitted. Devi- ating layout criteria must be secured by individual checks.●Oil coolers must be controlled by thermostats (see tablefor temperature settings).11IEC星-三角启动 星-三角启动 直接启动转 向Supply rotating fi eldIEC star delta start star delta start Direct on line start Y/△By applying a star-delta combination with closed transition system(additional contactor and resistom), the second current peak can be avoided.8.2 Compressor protection deviceThe CSH compressors are fi tted with the protection device SE-E1(Signal Evaluation - Enhanced).The protection device is build into the terminal box. The wiring to the motor and oil temperature PTC sensors and also to the motor terminals is factory mounted.Temperature monitoringThe SE-E1 locks out immediately if maximum allow-able temperatures for motor, discharge gas or oil are exceeded.Rotation direction monitoringThe SE-E1 monitors the rotation direction during the fi rst 5 seconds after compressor start.If the compressor starts with wrong rotation direction, the SE-E1 locks out immediately.Phase failure monitoringIn case of a phase failure during the fi rst 5 seconds after compressor start, the SE-E1 immediately opens the relay contact in the control circuit and closes again after 6 minutes. It locksout at:●3 phase failures within 18 minutes and / or●10 phase failures within 24 hours.应用闭式星-三角启动（需添加接触器和电阻）可 避免二次电流峰值8.2 压缩机保护装置CSH系列压缩机配有保护模块SE-E1（增强型）。
