5.9. Insulation tests
Before executing the insulation tests required by standards (EN81-20 item 5.10.1.3, EN81-20 item 6.3.2 c),
EN81-1 and EN81-2 item 13.1.3), you have to:
1. place the car out of floors
2. open mains switches
3. check that the automatic switch FA is closed
4. disconnect green-yellow wire from the RCF01 device
5. disconnect from the earth collector on the control panel any other conductor that has
not
protective function or equipotentiality
function (i.e. which is not green-yellow). Conductors with protective function are, for example, any connection to metal plates,
frames or enclosure of any electrical equipment, while conductors with equipotentiality function are connections to foreign
metallic parts, such as a metal pipe coming from the outside
6. if a VVVF drive or a soft starter device is used, please follow the instruction for insulation tests supplied by the manufacturer.
Generally, a short-circuit between the power terminals (all together) is required.
7. disconnect the phone line from the automatic phone dialer
8. disconnect the control panel from any other control panel belonging to an array of lifts
9. for any device not supplied by SEA SYSTEMS, always follow the manufacturer instructions. For example, if you use
VEGA B-
LIFT series 8120 evo
light curtain along with the
CPB12/24
control unit supplied by 0/24V coming from the STK1R control
panel, you have to disconnect the supply conductors of
CBP12/24
(DC IN terminals) before performing any test, because its
electrical circuits are not insulated from the ground (G terminal) and from the metallic frame of the light curtains.
The circuits that must be isolated from each other and the tests to be performed are summarized in the
following tables.

To simplify the measure, it is possible to perform the insulation test of this circuit only on the signal
“0”, which is available, for example, on terminals A0.1, A0.2 of the STK1R board. All other signals
are kept almost at the same voltage (within a few volt) by protective electronic devices provided on
all inputs and outputs.
