Easy Confirmation of Switch Settings Using Indicators The ON/OFF status of the DIP switch pins can be confirmed using the front display. Changes to DIP switch settings are enabled when the power is turned ON. When using time ranges that cannot be set with the DIP switch, all of the settings have to be made using the operation keys. For details on the setting methods, refer to page 27. Detailed Settings After making DIP switch settings for basic functions, detailed settings (see note) can be added using the operation keys. Note: NPN/PNP input mode, display color, key protect level. 26 Multifunction Digital Timer H5CX-A/-L (Twin Timer Function) Settings for Advanced Functions Settings that cannot be performed with the DIP switch are performed with the operation keys. Power ON Run mode For details on operations in run mode, refer to page 29. If the mode is switched to the function setting mode during operation, operation will continue. Changes made to settings in function setting mode are enabled for the first time when the mode is changed to run mode. Also, when settings are changed, the timer is reset (time initialized and output turned OFF). (See note 2. ) The characters displayed in reverse video are the initial values. When performing settings with operation keys only, set pin1 of the DIP switch to OFF (factory setting). If pin 1 of the DIP switch is set to ON, the setting items indicated by will not be displayed. OFF time range Set the OFF time range using the s s s keys. . . . . . . h s For details, refer to Time Range List below.

Only settings of type --. -- s (99. 99 s), ---. - s (999. 9 s), ---- s (9, 999 s), and -- min -- s (99 min 59 s), however, can be made with the DIP switch. Use the operation keys if another type of setting is required. Input Signal Width (iflt) (Setting possible using DIP switch. ) Set the minimum signal input width (20 ms or 1 ms) for signal, reset, and gate inputs. The same setting is used for all external inputs (signal, reset, and gate inputs). If contacts are used for the input signal, set the input signal width to 20 ms. Processing to eliminate chattering is performed for this setting. ON Time Range (ontr) (Setting possible using DIP switch. ) Set the time range for the ON time in the range 0. 001 s to 9, 999 h. Only settings of type --. -- s (99. 99 s), ---. - s (999. 9 s), ---- s (9, 999 s), and -- min -- s (99 min 59 s), however, can be made with the DIP switch. Use the operation keys if another type of setting is required. NPN/PNP Input Mode (imod) Select either NPN input (no-voltage input) or PNP input (voltage input) as the input format. [. . . ] Basic insulation between power supply and output terminals, and between input terminals and output terminals. When double insulation or reinforced insulation is required, apply double insulation or reinforced insulation defined in IEC 60664 that is suitable for the maximum operating voltage with clearances or solid insulation. Transistor Output The transistor output of the H5CX is insulated from the internal circuitry by a photocoupler, so the transistor output can be used as both NPN and PNP output. NPN Output PNP Output Load Load + + Power for load Power for load The diode connected to the collector of the output transistor is used to absorb inverted voltage that is generated when an inductive load is connected to the H5CX. Timer Inductive load + Power for load 48 Digital Timer H5CX Safety Precautions (H5CX-A/-L) CAUTION If the output relay is used beyond its life expectancy, its contacts may occasionally become fused or there may occasionally be a risk of fire. The life expectancy of the output relay varies considerably according to its usage. Use the output relay within its rated load and electrical life expectancy. [. . . ]
