alarm (fault status)
: Contact output is performed (off) when the amount of light transmis-
sion is insufcient.
: According to the preset upper or lower limit alarm value, contact
output is performed (off) when it becomes lower than alarm up-
per/lower limit.
: Contact output is performed (off) when laser failure, laser tempera-
ture control failure, exceeding the amount of light transmission or
connection error are occurred.
: While AO output is held by the hold setting, the values, output (off)
of which are held, are the ones just before the holding or arbitrary set
values. Contact output is performed (off) under calibration.
: Contact output is performed (off) when power is turned off.
applying rectangular-wave voltage (pulse width 2 sec or more) to the
input terminal of the average value resetting. Output is reset by in-
putting and restarted by opening.
: Switching to and from the instantaneous value and the average value
of the analog output is performed by applying rectangular wave
voltage (pulse width 2 sec or more) to the input terminal for switch-
ing between the instantaneous value and the moving average values.
: The analog output is held by applying rectangular wave voltage
(pulse width 2 sec or more) to the remote hold input terminal, and
restarted by applying it again.
