31.1. CALIBRATION OF SUPERVISED OUTPUTS (H5/A1)
Supervised (monitored) outputs:
The voltage outputs (S0-S3) in each control unit.
The voltage outputs (VO0-VO1) in the COM loop output unit 3364.
The voltage outputs (0-2) on the I/O exp. boards 4583.
When all alarm devices have been connected, including required end-of-line devices and when the SSD is downloaded, a calibra
-
tion has to be done.
FUNCTION
If the actual value at any time differs from the calibrated value ± a small tolerance or if the calibrated value is outside the calibration
range, a fault will be generated.
a) Log on to the c.i.e.
b) Navigate to menu A1.
c) Press
to start calibration of supervised outputs.
d) Press
again when the calibration is ready.
e) To exit the menu press ESC
.
After the calibration it is recommended to do a "Safe shutdown of the control unit", see menu H8/S5. This
will save the SSW data (e.g. the calibration values) in a Flash ROM.
31.1.1. END-OF-LINE DEVICES
Control unit outputs S0-S3, programmed as Supervised (1-50kΩ)
: One end-of-line resistor (33kΩ) in the last unit or one resistor
(33kΩ) in up to five units.
Control unit outputs S0-S3, programmed as Supervised (EN54-13)
: One end-of-line device 4472 in the last unit on the line
4583 outputs 0-1
: Calibration value range 4.7 kΩ - 40 kΩ.
3364 outputs (VO0-VO1)
: One end-of-line capacitor (470 nF) in the last unit or one capacitor (470 nF) in up to five units.
