1.3 Electrical Specifications
The power supply is SELV isolated, therefore all remote sensor and remote
switch wiring to the control does not need to be mains level rated, but should
be insulated to the highest voltage present where entering the control box.
Relay 1 is rated
16A/240Vac resistive
6A/240Vac inductive / fluorescent
3A/240Vac compact fluorescent
Relay 2 is rated
16A/240Vac resistive
6A/240Vac inductive / fluorescent
3A/240Vac compact fluorescent
Relays 1 and 2 are rated
16A/240Vac resistive
6A/240Vac inductive / fluorescent
3A/240Vac compact fluorescent.
Total maximum load for relays 1
and 2 is 12A.
Relays 3 to 7 are rated
10A/240Vac resistive
4A/240Vac inductive / fluorescent
2A/240Vac compact fluorescent.
Maximum load for each of relays
3 and 4 is 6A.
Total maximum load for relays 5
to 7 is 12A.
Generally, it is recommended that
the relays are used to operate
contactor relays. Using the
engineers menu, the relays can be
assigned en-masse to control
either as contacts open for lighting
on (normally closed contactors
required for fail safe operation) or
contacts close for lighting on
(normally open contactors
required).
0 – 10V signals:
A 0 to 10Vdc output signal is
provided for dimming control.
Output impedance is 50 Ohm and
maximum current drive capacity is
5mA. The output signal is not
isolated from the control circuit but
the common ground may be
Earthed.
Sensors can be sited up to 100m
from the control; the cable
may be screened to improve noise
rejection. Cable resistance must be
less than 10 Ohms to minimise
errors.
