3.3  DEVICE CONTROL

 ADDR.  WORD  CONTENTS
  801 

Bank No.

 

 

 

Different sets of alarm setpoints and properties (Banks) can be selected when Master writes 1 ... 8.

 

 

 

In order to activate this setting, Bank Switching via communication must be enabled at Register 4009.

 

 

 

This register is reset to ‘1’ at the device startup.

  802 

Reset MIN / MAX values

 

 

 

MIN / MAX reading currently on the display is reset when ‘1’ is set.

 

 

 

The register value is automatically reset again to ‘0’ when the MAX / MIN value resetting action is complete.

 

 

 

If another value is set before ‘0,’ the resetting result becomes undefined.

 

3.4  LOCKOUT SETTING

 ADDR.  WORD  CONTENTS
  901 

Modbus register access control

 

 

 

0 : Read only (*)

 

 

 

1 : Write enabled

 

 

 

This register is reset to ‘0’ at the device startup.  Write ‘1’ before starting writing other registers.

 

 

 

Once ‘1’ is set, alarm and analog outputs are held at the last value and status before it has been turned ‘1.’

 

 

 

With ‘0,’ these outputs respond to the input signal.
