4.5.3.1 Alarms
Refer also to Figure 8 on page 18 and Table 5 on page 19. Alarm threshold relays
(K2 and K3) are set to normally open (NO). The system alarm relay (K1) can be set to
normally open (terminals 16 and 17) or normally closed (terminals 16 and 18).
4.5.3.2 Analog outputs
Refer also to Figure 8 on page 18 and Table 3 on page 19. The analog outputs 0-20 mA
or 4-20 mA are galvanically insulated. The following table shows the allocation of the
different outputs:
1 channel analyzer 2 channel analyzer
I out 1 Terminal 1-2 of J9 Channel 1
I out 2 Terminal 3-4 of J9 Measurement potential
I out 3 Terminal 5-6 of J9 Not used Channel 2
4.5.3.3 Sample level detector
Refer also to Figure 8 on page 18 and Table 2 on page 19. The reactor is equipped with a
sample level detector. Wire the connection to J8 as follows:
J8 Terminal number Color
1 Brown
2 Green
3 Yellow
4 White
4.5.3.4 Reagent level detector
Refer also to Figure 8 on page 18 and Table 2 on page 19. Each reagent canister is
equipped with a level detector. For each reagent, wire the connections to J4, J5, J6 and
J7 as follows:
