Space Heater - Test
Cat 发电机可以在湿度高的环境下工作没有问题。 但是当发电机怠速和在周围空气温度比发电机高时就会产生问题。 水气可能在绕组上形成，这将使绕组的性能降低。 水气还能损坏绕组。 只要发电机不运转时，就应确保空间加热器运转。

- 停下发电机组。
- 拆下面板以接近调速器和控制接线排端子。 将接线排端子 "TS1"固定。
- 对240 V系统，用万用表测量端子"H1" 和 "H4" 之间的电压。. 如果不存在电压，则将端子 "H1" 和 "H4" 的电源断开，检查是否存在 3 ~ 12 欧姆的电阻。 如果不存在电阻，查看发电机维修手册中的资料。 对于120 V 系统，用万用表测量端子 "H1" 和 "H2" 之间的电压。 如果不存在电压，则将端子 "H1", "H2", "H3" 和 "H4" 的电源断开，检查是否存在 3 ~12 欧姆的电阻。 如果不存在电阻，查看发电机维修手册中的资料。
