Input

Digital inputs: they accept PNP type sensor or switches connected to the

positive. The sensor/switch has to be supplied at battery voltage.

Analog inputs: Mhyrio provides 1 analog input. The analog device can be

supplied at +5 V or +12 V. It is necessary to specify in the order the voltage

selected. The supply output is able to deliver max 100 mA.

ON-OFF valves drivers programmable. They can drive the coil in full conduction

or in PWM mode in order to supply the coil at the nominal programmed voltage

independently by the battery voltage. See related parameter in ‘Set Option’ menu.

Proportional valves are driven in current mode with programmable frequency.

The valves voltage supply is the same used for ON-OFF valves and the current

range have to be defined. Via handset it is adjustable in a big range, but the

shunts can be adapted to every types of valves (minimum current 200 mA,

maximum current up to 2 A).

Analysis of alarms displayed on the console

1) EEPROM KO

Fault in the area of memory where the adjustment parameters are stored.

This Alarm does not inhibit machine operation but operation goes on with

default values; if fault is still present when the Key Switch is re-cycled,

replace the logic. If the fault disappears, the previously stored Parameters

will have been replaced by the default parameters.

2) CAN BUS KO

There is a problem related to the CAN-BUS line. The error is signalled if the

MHYRIO controller does not receive any message from the CAN-BUS line.

First of all, check the wiring. If it is ok, the problem is on the logic board,

which must be replaced.

3) WATCHDOG

The test is made in both running and standby. It is a self-diagnosing test

within the logic. If an alarm should occur, replace the logic.

4) WRONG SET BATTERY

This fault is signalled if the battery voltage is non consistent with the set

battery programmed in the ‘set option’ menu.

5) UNDERVOLTAGE

This fault is signalled if an undervoltage condition is detected in the MHYRIO

power supply.

6) FF VALVES

Flip-flop circuit, that manages on/off valve drivers short-circuit protection,

does not reset in the correct way. The problem is probably in the hardware

circuit.

7) COIL SHORTED

ON/OFF valves drivers are protected against coil short circuit; if a short is

present across the coil, the flip-flop circuit is set and the alarm is signalled.

8) EV DRIVER SHORT

One of the on/off valves driver is shorted; check the external connection, if it

is ok the driver is probably damaged.

9) EVP DRIVER SHORT

The single proportional valve driver is shorted; check the external connection,

if it is ok the driver is probably damaged.

10) EVPG1 DRIVER SHORT

One of the Group 1 valves drivers is shorted; check the external connection,

if it is ok the driver is probably damaged.

11) EVPG2 DRIVER SHORT

One of the Group 2 valves drivers is shorted; check the external connection,

if it is ok the driver is probably damaged.

12) EVPG3 DRIVER SHORT

One of the Group 3 valves drivers is shorted; check the external connection,

if it is ok the driver is probably damaged.

13) EVPG4 DRIVER SHORT

One of the Group 4 valves drivers is shorted; check the external connection,

if it is ok the driver is probably damaged.

14) EV DRIVER KO

One of the On/Off valves drivers is open (it does not close when it is
