iSWAY-FC, iSWAY-WFC, iSWAY-RFC. To do this, follow these steps:
1.
Check the position of the main switch ("0" switched off, "1" switched on)
2.
Check the status of the 1H1 "Power Control" light on the enclosure cover SzA-FCP/K.
In the absence of light signalisation, proceed with the checks in point 3.
3.
Check the status of the 1K1 phase control relay in the SzA-FCP/K cabinet. The red color of
the LED on the relay indicates incorrect phase sequence or no phase. In this case, first
perform the steps of point 3.
If the supply voltage is found to be correct, you should
•
turn off the power,
•
change the connection sequence of phase 1 and 2 wires on the terminals of the XZ1
strip of the power supply and control cabinet SzA-FCP/K
•
turn on the power,
4.
Check the phase supply voltage (230V +/- 5%) and the interphase supply voltage (400V +/-
5%) at the terminals of the XZ1 strip of the SzA-FCP/K power supply and control cabinet
based on the electrical design. If the measured voltage values deviate from the permissible
parameters, discontinue further commissioning and notify the relevant technical service
on site.
5.
Check that the shut-off damper is in the fully closed position (damper blade in the
perpendicular position to the direction of air flow, actuator indicator in the position
+85;+95[°]).
6.
Check 24V (+/- 10%) at the terminals of the power supply and control cabinet SzA-FCP/K
(based on the cabinet design). If the measured voltage values deviate from the permissible
parameters specified in the DTR of the power supply, it is necessary to start service
activities, based on the technical documentation of the power supply, aimed at diagnosing
and removing the failure.
7.
Check the status of the controls on the automation components:
•
MAC-FC controller power light, and current status of the MAC-FC front panel LEDs
•
UG-3-A4O channel housing smoke detectors
In case of lack of power supply signalling for the mentioned devices, it is necessary to start
service activities, based on the device's technical documentation, aimed at diagnosing and
removing failures.
8.
Check the state of supply of the actuator(s) of the shut-off damper by visual inspection of
the actuators (after the voltage is applied, the dampers should go to the closed position -
in about 150 seconds - damper blade in the position perpendicular to the direction of air
flow, the indicator of the actuator in the po85;+95[°])
9.
Check the correct operation of TSS or TS indicators and display:
