mode and the door monitoring sensor doesn’t normal closed as
the door is held. In such condition, the door release driver will
shut off the relay driver once it found
the door is opened because the door sensor is left opened.
Therefore, please replace the sensor or set the door monitoring
mode as 1100 (not monitoring) before you
replace the sensor.
A.2—If the door released period is not so long as you set by 21tt, but
you have already disabled the door monitoring function by 1100
or although you actuate the door monitoring by code 1101, but
the door sensor works normally, then this phoenomena is resulted
from the EMI interference from the drivered electrical device
usually. If the coil of the door actuator or the external relay
doesn’t well protected by a reversed polarity free wheeling diode
to suppress the interference for DC voltage driver or a surge
absorber for AC voltage driver, the voltage transient pulse will let
theCPU hold down or run into disorder or automatic reset and
therefore shorten the door released time to around one second.
#Symptom 05:
The counter can’t be set by F9 counter setting
A.1—At first, if the address 880n is properly set. If the system address
isn’t properly set (Can be checked by “0” key) or is disturbed,
then the reader won’t store the event counter.
Questions concerning the card reader and its on-lined controller
(Any brand of PC or other dedicate controller)
#Symptom 01:
The Personal Computer can not collect the data string
from the reader(s) by standard software package.
A.1—At first, for on-lined application, the installer should ultilize the
terminal simulation software package such as TELEX,BITCOM
etc. to test whether the wiring between the PC (and
the
Multi-channel controller PCP-832-xx or the RS-422/RS-232C
converter or other 3rd partners interfacing devices for networking)
and the readers are well connected and the communication
parameters are selected correctly. At the same time, each reader
should be set the correct parameters, unique reader address for
each reader at the same wire cable for address mode by 88nn,
890n or 8900 for batch type or 890t for real time type…, etc. The
reader address can definitely not be set the same for any two
readers.The installer should be able to judge whether the wiring is
