2.2 Main board: description of the terminals
Below is the wiring diagram for the MPXPRO main board in the version
with 5 relays. The connectors are screen printed to simplify the electrical
connections.
Terminal Description
30 GND Multifunction analogue/digital input
• NTC, PTC, PT1000, NTCL243 probe
• Multifunction digital input
32 S5/DI2
33 S4/DI1
34 GND
NTC/PTC/PT1000/NTCL243 probes
35 S3
36 S2
37 S1
Note:
• Depending on the model, the main board may have two open
collector/PWM analogue outputs for connecting:
1. PWM1: phase - cutting controllers (e.g. MCHRTF****) for inductive loads
(e.g. evaporator fans with inductive motors for optically-isolated
control);
2. PWM2: SSR relay for the anti-sweat heaters on the display cases;
• The devices with 4 to 20 mA or 0 to 10 Vdc output connected to input
S7 cannot be powered directly from the MPXPRO. They therefore
require an appropriate external power supply.
Important:
• The type of input connected to each probe in the same group can be
confi gured by just one parameter. For each group 1(S1,S2,S3)-2(S4,S5)-
3(S6)-4(S7), there is just one parameter that defi nes the type of input,
and consequently this must be the same for all the probes in the same
group. For group 2, S4 and S5 can be confi gured as probes yet operate
as digital inputs.
• All the contacts should be galvanically insulated by adding further relays
for each contact. The digital inputs must not be connected in parallel,
otherwise the board may be damaged.
Note: before performing any operations on the control board,
disconnect the main power supply by turning the main switch in
the electrical panel OFF.
