Calibration of Supervised Outputs (H5/A1)
Supervised (monitored) outputs

:
•
The voltage outputs (S0-S1) in the control unit
•
The voltage outputs (VO0-VO1) in the COM loop output unit 3364.
•
The voltage outputs (Output 0-Output 1) on the I/O expansion board 4583
When all alarm devices (OWS, sounders, etc.) are connected, including required End-Of-
Line devices
65
and when the SSD download is ready, a calibration has to be done.
Function : If the actual value differs from the calibrated value ± a small tolerance or if the
calibrated value is outside the calibration range
66
, a fault will be generated.

Note: During the calibration, all outputs will automatically be low, i.e. a normally high
output will be low during the calibration for a few seconds.
Note: After the calibration it is recommended to do a "Safe shutdown of control unit" (see
menu H8/S4). This will save the SSW data (e.g. the calibration values) in a Flash ROM
(see page 82).

Supervised (monitored) outputs can be set to be not supervised via EBLWin.

FT128 outputs (S0-S1) requires one EOL resistor (33K) in the last unit or one resistor (33K) in up to five units, 3364 outputs
(VO0-VO1) requires one EOL capacitor (470 nF) in the last unit or one capacitor (470 nF) in up to five units.

4K7 – 50K and 470 – 5x470 nF respectively.
