User manual OMRON H5CX

[. . . ] Digital Timer H5CX Please read and understand this catalog before purchasing the products. Please consult your OMRON representative if you have any questions or comments. Refer to Warranty and Application Considerations (page 52), and Safety Precautions (page 47). DIN 48 ´ 48-mm Multifunction Digital Timer/2-stage Digital Timer · Highly visible display with backlit negative transmissive LCD. · Finger-safe terminals (screw terminal block models). [. . . ] Changes to DIP switch settings are enabled when the power is turned ON. (Perform DIP switch settings while the power is OFF. ) 3. For details on the setting methods, refer to page 27. 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. ON time range Set the ON timer range using the s s s keys. . . . . . . h s For details, refer to Time Range List below. Timer mode Set the timer mode using the keys. (Elapsed (Remaining time) time) Function setting mode ON/OFF start mode Set the twin timer output mode using the keys. (Flicker OFF (Flicker ON start) start) Set the input signal width using the keys. Time Range List Display Set Value 0. 01 s to 99. 99 s (default setting) 0. 1 s to 999. 9 s 1 s to 9999 s Input signal width (20 ms) (1 ms) NPN/PNP input Set the NPN/PNP input mode using the keys. 0 min 01 s to 99 min 59 s 0. 1 min to 999. 9 min 1 min to 9999 min (NPN input) (PNP input) Only displayed for H5CX-A@ and H5CX-A11@ models. Set the display color using the keys. Display color 0 h 01 min to 99 h 59 min (Red) (Green) (Red-green) (Green-red) Displayed for terminal-block models (H5CX-A@) only. Key protect level Set the key protect level using the keys. 0. 1 h to 999. 9 h 1 h to 9999 h 0. 001 s to 9. 999 s (KP-1) (KP-2) (KP-3) (KP-4) (KP-5) Multifunction Digital Timer H5CX-A/-L (Twin Timer Function) 27 Explanation of Functions OFF Time Range (oftr) (Setting possible using DIP switch. ) Set the time range for the OFF time in the range 0. 000 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. 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. [. . . ] Depending on the wiring, unwanted current from the AC power supply may occasionally burn out (damage) the internal parts. The H5CX-A/-L (except for H5CX-A11/-A11S) do not have transformers. Therefore, there is no insulation between the power supply and input terminals, so make sure that wiring is correct before use. For the power supply of an input device of the H5CX (except for H5CX-A11/-A11S), use an isolating transformer with the primary and secondary windings mutually isolated and the secondary winding not grounded. Precautions for Safe Use Usage Precautions Do not touch the input terminals while power is supplied. [. . . ]
