■Characteristics
Note: 1. The values are based on the set value.
2. The value is applied for a minimum pulse width of 1 ms.
3. To meet UL listing requirements with the H5CX-L8@, an OMRON P2CF-08-@or P3G-08 Socket must be mounted on the Timer.
4. A waterproof packing is necessary to ensure IP66 waterproofing between the H5CX and installation panel.

H5CX (Timer Function)H5CX (Timer Function)
■Explanation of Functions
Time Range (timr) (Setting possible using DIP switch.)
Set the range to be timed in the range 0.000 s to 9,999 h. Settings
of type ---- h (9,999 h) and ---- min (9,999 min) cannot, however,
be made with the DIP switch. Use the operation keys if these set-
tings are required.
Timer Mode (timm) (Setting possible using DIP switch.)
Set either the elapsed time (UP) or remaining time (DOWN)
mode.
Output Mode (outm) (Setting possible using DIP switch.)
Set the output mode. The possible settings are A, A-1, A-2, A-3,
b, b-1, d, E, F, and Z. Only output modes A, A-2, E, and F can be
set using the DIP switch. Use the operation keys if a different set-
ting is required. (For details on output mode operation, refer to
Timing Charts on page 20.)
Output Time (otim)
When using one-shot output, set the output time for one-shot out-
put (0.01 to 99.99 s). One-shot output can be used only if the
selected output mode is A, A-1, A-2, b, or b-1. If the output time is
set to 0.00, hold is displayed, and the output is held.
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.
NPN/PNP Input Mode (imod)
Select either NPN input (no-voltage input) or PNP input (voltage
input) as the input format. The same setting is used for all exter-
nal inputs. For details on input connections, refer to Input Connec-
tions on page 28.
Display Color (colr)
Set the color used for the present value.
Key Protect Level (kypt)
Set the key protect level.
When the key-protect switch is set to ON, it is possible to prevent setting errors by prohibiting the use of certain operation keys by specify-
ing the key protect level (KP-1 to KP-5). The key protect indicator is lit while the key-protect switch is set to ON.
Note: Changing mode to timer/twin timer selection mode ( + 1 s min.) or function setting mode ( 3 s min.).

■Operation in Run Mode
Present Value and Set Value
These items are displayed when the power is turned ON. The
present value is displayed in the main display and the set value is
displayed in the sub-display. The values displayed will be deter-
mined by the settings made for the time range and the timer mode
in function setting mode.
Present Value and ON Duty Ratio (Output Mode = Z)
The present value is displayed in the main display and the ON
duty ratio is displayed in the sub-display. “SET1” lights at the
same time.
Set the ON duty ratio used in ON/OFF-duty adjustable flicker
mode (Z) as a percentage.
If a cycle time is set, cyclic control can be performed in ON/OFF-
duty adjustable flicker mode simply by changing the ON duty ratio.
ON time = Cycle time

The output accuracy will vary with the time range, even if the ON
duty ratio setting is the same. Therefore, if fine output time adjust-
ment is required, it is recommended that the time range for the
cycle time is set as small as possible.
Examples:
1. If the cycle time is 20 s, the ON duty ratio is 31%, and the
time range is 1 s to 9999 s, the ON time is given by the fol-
lowing:
20 (s)
 = 6.2 (s)  Rounded off to the nearest
integer (because of the time range setting)
 ON time = 6 s
2. If the cycle time is 20.00 s, the ON duty ratio is 31%, and
the time range is 0.01 s to 99.99 s, the ON time is given by
the following:
20.00 (s)
 = 6.200 (s)  Rounded off to 2 decimal
places (because of the time range setting)
 ON time =
6.20 s
Present Value and Cycle Time (Output Mode = Z)
The present value is displayed in the main display and the cycle
time is displayed in the sub-display. “SET2” lights at the same
time.
Set the cycle time used in ON/OFF-duty adjustable flicker mode
(Z).

Operation (Twin Timer Function)
■Switching from Timer to Twin Timer
The H5CX is factory-set for timer operation. To switch to twin timer operation, use the procedure given below. For details, refer to page 35.
■Settings for Basic Functions
Note: All the pins are factory-set to OFF.
Easy Confirmation of Switch Settings Using Indicators
The ON/OFF status of the DIP switch pins can be
confirmed using the front display. For details, refer to page 19.
Note: 1. Be sure to set pin 1 of the DIP switch to ON. If it is set to OFF, the DIP switch settings will not be enabled.
2. Changes to DIP switch settings are enabled when the power is turned ON. (Perform DIP switch settings while the power is OFF.)
3. There is no DIP switch on the H5CX-L8@. For details on the setting methods, refer to page 16.
4. 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 16.

■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 set-
ting is required.
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.
Timer Mode (timm) (Setting possible using DIP switch.)
Set either UP (incremental) or DOWN (decremental) timer mode.
In UP mode, the elapsed time is displayed, and in DOWN mode,
the remaining time is displayed.
ON/OFF Start Mode (totm) (Setting possible using DIP
switch.)
Set the output mode. Set either flicker OFF start or flicker ON
start. (For details on output mode operation, refer to Timing
Charts on page 20.)
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.
NPN/PNP Input Mode (imod)
Select either NPN input (no-voltage input) or PNP input (voltage
input) as the input format. The same setting is used for all exter-
nal inputs. For details on input connections, refer to Input Connec-
tions on page 28.
Display Color (colr)
Set the color used for the present value.
Key Protect Level (kypt)
Set the key protect level.
When the key-protect switch is set to ON, it is possible to prevent setting errors by prohibiting the use of certain operation keys by specify-
ing the key protect level (KP-1 to KP-5). The key protect indicator is lit while the key-protect switch is set to ON.
Note: Changing mode to timer/twin timer selection mode ( + 1 s min.) or function setting mode ( 3 s min.).
