PMH Timers (Discontinued Products)

Cautions For Use

• In order to maintain the characteristics of PHM timer, do not remove the case.
• Please use within an ambient temperature range of -10 to +50 ℃ +14 to 122 ℉ and in humidity no greater than 85 % RH.
• Prevent using PMH timer in such places where flammable or corrosive gas is generated, a lot of dust exists or considerable shock and vibration occur.
• Since the main body cover and knob are made of polycarbonate resin, prevent contact with organic solvents such as methyl alcohol, benzene and thinner, or strong alkaline materials such as ammonia and caustic soda.
• Do not make direct solder connections to the round pins.
• Carefully verify the terminal numbers when wiring the terminal socket and cap.
• When rotating the knob, note that there are stoppers located just past the "0" side and the full scale side. Therefore, do not use unreasonable force.
• Please use with a time setting that is no less than the minimum time limit. The minimum time limit is indicated on the dial by the mark.
• The contacts will not operate if the needle is adjusted to the "0" position when the power is off.
• Phase synchronization for AC load switching When timer output contact will be synchronized to the AC power phase, the electrical life may be compromised and locking (contact reset failure) may occur due to contact welding or contact transference. Therefore, please conduct tests using actual equipment.
