7.3 Fixed outputs
10.3.1. Control signal outputs
Control signal outputs are the output orders (dry contact) to the RTSE; the
ATSC25 includes 3 signal outputs and a common (point powered by the user)
(Terminals 17 to 14). These outputs are rated for 250 Vac, 50/60 Hz 5A general
use , and 30 V.d.c 5A general use.
These outputs function as described below:
When order 0 is given through the Automatism in automatic mode or manually using the button the contact between
17 and 16 will be closed.
When order I is given through the Automatism in automatic mode or manually using the button the contact between
17 and 14 will be closed.
When order II is given through the Automatism in automatic mode or manually using the button the contact between
17 and 15 will be closed.
These outputs can be impulse or maintained depending on the setting on DIP switch 3 Order Mod.
In maintained mode when an order is sent it will be maintained until a different order is sent.
In impulse mode orders are sent for maximum 5s and are stopped when either 5s has expired or the controller received feedback
that the RTSE has reached the requested position. If 5s expire and the RTSE has not reached the requested position the
controller will consider this as a fault and will inhibit the automatism until the fault is cleared.
10.3.2. Genset start output
Genset start outputs are the output orders (dry contact), the contact between 51 and 54
will open & the contact between 51 and 52 will close when the signal to start the genset
should be sent (during a test on load or when source 1 is lost). These outputs are rated for
250 V.a.c, 50/60 Hz 5A general use for NO contact and 3A general use for NC contact,
and 30 V.d.c 5A general use for the contact between 51-54 and 3A general use for the
contact 51-52.
Control 51/54 51/52
Generator Start Contact open Contact closed
Generator Stop Contact closed Contact open
When the switch returns in position I the Cooldown timer will start counting (Default value 180s) during the cooldown timer, the
contacts will maintain the generator start signals.
If the 24 V.d.c auxiliary power supply is not used the timer 1FT will not count and the
order to start the generator will be sent immediately when source 1 is lost.
