10.3 Settings
When the KITZ interface unit is used to allow a PC (running master station
software) to communicate with K Range relays (ie. normal operation), the
following applies:
Check baud rate (option switches 0-2) setting on the IEC-870 (RS232) port
corresponds to the data communication rate of the master station. The standard
setting is 9600 bps and the following option switch position apply:
Option Switch 0 is set to 1 (Up)
Option Switch 1 is set to 1 (Up)
Option Switch 2 is set to 0 (Down)
Option Switch 3 (RS232 (IEC870) frame format) should be set to the 0 (Down)
position.
Option Switch 4 (Add IEC time-tag) should be set to the 1 (Up) position.
Option Switches 5 and 6 (Modem Present and Modem Set-up) should be set to
the 0 (Down) position.
Option Switch 7 (reserved) should be set to the 0 (Down) position.
The option switch settings are applied at power-up.
If changes are made to the settings, the auxiliary supply must be switched off.
The unit is re-energised after at least 5 seconds.
Section 11. PROBLEM SOLVING
Common operational faults are listed in this section. The solutions offered are for
guidance only.
11.1 Green supply indication led is off
Check correct auxiliary supply is present (ie. no supply).
Check fuse.
11.2 Fuse blows on power-up (KITZ 101 only).
Check that excessive auxiliary supply voltage is not being used.
11.3 IEC 870 receive indication is off when communicating with a master station
Check data rate selection for IEC-870 (RS232) port is identical to that of the
master station.
Power-down the unit and then power-up the unit to guarrantee the switch settings.
Check master station is polling for data.
11.4 K-Bus receive indication is off when communicating with a master station
(and K relay)
Relay is not communicating (incorrect address/not configured etc.): refer to the
appropriate K Range service manual.
