block and remove the panel. Contacts should be inspected and replaced if badly pitted. On contacts, other than silver-plated ones, a coating of nonoxide grease is desirable. When grease cups are provided for the front and rear motor bearings, the grease cups should be given a half turn every 3 months. The manufacturer's recommended grease should be used for refilling. The clock mechanism should be overhauled every 5 years by the manufacturer or a competent watchmaker.

b. Contactors. Contactors are described under chapter 11, section II.

c. Photo cells. Any dust or dirt on the windows of photo controls of any type will prevent proper opera­tion. These windows must be kept clean.

(1) Self-generating phototronic photo cell. The self-generating phototronic cell has a normal clear day output of 1.5 to 6 milliamperes. It can operate the relay on 0.5 milliampere, so replacing the light collector is not necessary until its output tests below 0.5 milliampere. Any testing should be made on a cloudless day using a milliammeter with a range of 0 to 10 milliamperes. The check can be made most conveniently at the terminals on the relay box. When the output of the light collector tests less than

0.5 milliampere, it should be returned to the manu­facturer for rehabilitation, or replaced with a photo-conductive cell. The relay for a phototronic cell is very delicate because of the small amount of energy needed to operate it.
