■ Basic Setting ■ Using the Setting Ring Setting of Selector Setting a Specific Time The selectors can be turned clockwise and counterclockwise to select the desired time unit, time range, output type (only for H3BAN8H) or operating mode. Each selector has a snap mechanism that secures the selector at a given position. Set the selector at a position at which it is secured. Do not set it midway between two securing positions or a malfunction could result from improper setting.
■ Timing Chart Note: 1. The minimum power-opening time (“Rt”) is 0.1 s and the minimum pulse width is 0.05 s. 2. The letter “t” in the timing charts stands for the set time and “t–a” means that the period is less than the time set.

End Plate Time Setting Ring/Panel Cover PFP-M 10 6.2 1 50 1.8 1.8 35.5 35.3 There are three types of Panel Covers (Y92P-48GL, Y92P-48GB, and Y92P-48GM), all of which are available in three colors. Use the most suitable type of Panel Cover with the design of the scaling plate according to the application. When setting a given time for the Timer, use of the Y92S-27 or Y92S-28 Time Setting Ring facilitates the time setting operation and minimizes possible setting errors by operators.

Safety Precautions CAUTION Minor electric shock may occasionally occur. Do not disassemble the product or touch the interior of the Timer. Minor burns may occasionally occur. Do not touch the product while power is being supplied or immediately after power is turned OFF. Minor fires may occasionally occur. Tighten terminal screws to a torque of 1.08 N·m so that they do not become loose. Minor electric shock may occasionally occur during operation. Install the terminal cover.
Operating Time Setting ■ Mounting When setting the operating time, do not turn the setting knob beyond its scale range. For precise time setting, conduct operation tests by adjusting the setting knob. Surface Mounting The accuracy of the operating time of the Analog Timer is indicated by the percentage value on the basis of the full-scale time. The absolute fluctuation value will not be improved by changing the time setting.
■ Dismounting PL Socket 1. Secure the Socket to the panel surface with screws and insert the F-shaped hook into the sockets. Surface Mounting with P2CF 2. Connect the Timer to the Socket and press the tip of each hook by hand. Panel Mounting Loosen the screws of the Flush Mounting Adapter, spread open the hooks, and remove the Mounting Adapter.
