Explanations of Functions
Time Range (
timr
)
Set the range to be timed in the range 0.000 s… 9,999 h. Use the operation
keys if these settings are required.
Timer Mode (
timm
)
Set either the elapsed time (UP) or remaining time (DOWN) mode.
Output Mode (
outm
)
Set the output mode. The possible settings are A, A-1, A-2, A-3, B, B-1, D, E,
F, and Z. (For details on output mode operation, refer to “Timing Charts” on
page 3-10.)
Output Time (
otim
)
When using one-shot output, set the output time for one-shot output (0.01…
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
)
Set the minimum signal input width (20 ms or 1 ms) for signal and reset
inputs. The same setting is used for all external inputs (signal and reset). 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.
Key Protect Level (
kypt
)
Set the key protect level.
When the key-protect switch in set to ON, it is possible to prevent setting
errors by prohibiting the use of certain operation keys by specifying the key
protect level (KP-1 to KP-5). The key protect indicator is lit while the
key-protect switch is set to ON. Confirm the ON/OFF status of the
key-protect switch after the 700-HX is mounted to the panel.
