Description of Levels
Operation Level
N This level is displayed when you turn the power ON. You can move to the protect level, initial
setting level, and adjustment level from the operation level.
N Normally, select this level during operation.
N During operation, the present value, set value, totalizing count value, and setting number of
SV-bank can be monitored using the
key.
Publication 700-UM001A-EN-D - June 2001
3-4
Application Examples
Adjustment Level
N To select this level, press the
key once for less than one second.
N This level is for entering set value (SV 0…3) for operation. This level contains parameters for
set value of SV-bank, and cycle time (timer Z mode).
N You can move to the top parameter of the operation level, protect level, or initial setting level
from here.
Initial Setting Level
N To select this level, press the
Key for at least three seconds in the operation level or
adjustment level.
N This level is for selecting the function, input mode, time range, timer mode, output mode,
output time, counting speed, input signal width, decimal point position, prescale value, and
rising/falling edge for input signal.
N You can move to the advanced function setting level from this initial setting level. To return to
the operation level, press the
key for at least one second.
Protect Level
N To select this level, simultaneously press the
and
keys for at least three seconds
(default value). This level is to prevent unwanted or accidental modification of parameters.
Protected levels will not be displayed, and so the parameters in that level cannot be modified.
Advanced Function Setting Level
N To select this level, you must change the initial settings in the protect level to "0" and then
enter the password ("-169") in the initial setting level.
N This level is for initializing settings, enabling SV-bank and totalizing counter use, setting
display auto-return time, and move- to-protect-level time.
N You can move to the initial setting level from this level.

Turn the power OFF and ON again. If
normal operation is still not restored, it
may be necessary to repair or replace the
700-HXM Digital Timing Relay/Counter. If
normal operation is restored by turning
the power supply OFF and ON, it is
possible that there is noise interference.
Check that there is nothing in the vicinity
that may be the source of noise.
This is not an actual error. This display
indicates that the present value has
dropped to a value less than -999. Reset
using reset input or pressing the Up Key
when "- - - -" is displayed.
