4.2.2 Logical processing of EASY-E4-UC controller inputs signals
The automaton includes 2 parts: one basis 12RC1 (B) + one extension 8RE1 (E), items B and E in inputs
names here below.
Input Name Action Priority
(0=highest)
LS comfort order Switch to LS comfort if HS or O not requested. 5
HS comfort order Switch to HS comfort if O not requested. 4
Comfort shuto Shuto in comfort mode. 3
Emergency Switch to smoke extraction mode (HS). 1
I5E Reset Switch from smoke extraction to comfort mode (only when
pressed) if the emergency command is not active. 2
I6E Thermal relays motor 1 (LS and
HS auxiliary contacts in series) If activated ► in comfort mode only, cuts motor 1 (MASTER and
connected SLAVE(S)) and fault indicator active. 3
I7E Thermal relays motor 2 (LS and
HS auxiliary contacts in series) If activated ► in comfort mode only, cuts motor 2 (MASTER and
connected SLAVE(S)) and fault indicator active. 3
I8B Thermal relays of
SLAVE(S) connected to motor 1 If activated ► in comfort mode only, cuts motor 1 (MASTER and
connected SLAVE(S)) and fault indicator active. 3
I1E Thermal relays of
SLAVE(S) connected to motor 2 If activated ► in comfort mode only, cuts motor 2 (MASTER and
connected SLAVE(S)) and fault indicator active. 3
I2E Emergency shuto In comfort and smoke extraction mode: shuts o the fan,
regardless of the state of the other inputs; fault indicator active
and smoke extraction indicator ashing. 0
I3E INTZ = switch-disconnector of
MASTER or SLAVE(S) or fan(s) In comfort or smoke extraction mode: The fault indicator is active
because the switch-disconnector(s) are open. 6
I4E Airow controller Fault indicator is active as the HS ow controller(s) is (are) not
activated on the fan aeraulic system controlled by MASTER or
SLAVE(S) despite a HS comfort or smoke extraction request. 6
4.2.3 Assignment of EASY-E4-UC controller outputs
The automaton includes 2 parts: one basis 12RC1 (B) + one extension 8RE1 (E), items B and E in out-
puts names here below.
Output Name Action
Q1B Fault indicator
Remains on when:
• Switch-disconnector(s) open on MASTER or on SLAVE(S) or fan(s).
• No detection of airow despite an “on” request (HS comfort or smoke
extraction).
• Emergency shuto activated.
• Thermal fault detected (in comfort mode only).
Fault reporting KA2 relays Only on the PILOT PARC “CMSI” version: “waiting” information reporting
for re protection system centralizer (connect contact with max. 48V/1A).
Q2B Smoke extraction indicator Remains on: Smoke extraction mode active.
Flashing: Emergency shuto requested in smoke extraction mode.
Smoke extraction reporting KA3 relays Only on the PILOT PARC “CMSI” version: “emergency” information
reporting for re protection system centralizer (connect contact with
max. 48V/1A).
LS output Motor 1 LS control of fan 1 + connected SLAVE(S).
HS output Motor 1 HS control of fan 1 + connected SLAVE(S).
Auxiliaire motor ON output Active if "Q3B or Q4B or Q3E or Q4E is active".
Auxiliary motor HS output Active if "Q4B or Q4E is active".
LS output Motor 2 LS control of fan 2 + connected SLAVE(S).
HS output Motor 2 HS control of fan 2 + connected SLAVE(S).
