ABB ICDG32L1 GJR5251400R0101 Transmission module

Description

Typically the two operator station function is used for a crane that is controlled by a radio remote unit and a local

console on board the crane.

Actuation of a Process DI will:

• Make the ASTAT taking command from either of the two stations.
• The indications (DO and AO) will remain for both stations at the same time.

The change of operator station is only allowed to change when the system is OFF.

Process I/O digital input no.3 can be used in two ways:

3) To select between operator stations

4) To make the selection between parameter sets 1 or 2 (Low sets family) or parameter sets 3 or 4 (High sets

family)-selection within the family is done by Process I/O digital input no.4.

With 05.27 = 0, a high value (=110 V) on DI no.3 on process I/O board DATX 110 will use DI no.3 to select between

operator station number two out of number one and number two.

With 05.27 = 1, a low value (=0 V) on DI no.3 on process I/O board DATX 110 will use parameter sets 1 and 2. The

selection between Sets 1 and 2 is made with DI no.4.

With 05.27 = 1, a high value (=110 V) on DI no.3 on process I/O board DATX 110 will use parameter sets 3 and 4.

The selection between Sets 3 and 4 is made with DI no.4.

NB! Do not mix this function with Shared motion, although related. The second parameter set function is typically used

for redundant motions, there, as an example; the acceleration ramps are lower when only half of the motors are used.

All uncontrolled stops of a crane should by subject to investigation. Typical reasons for uncontrolled stops are Over

speeding a hoist, Hitting upper safety limit switch or an Emergency stop push-button is pressed during run. In all

cases the reason should be reported and the reason should if possible be prevented from being repeated. Exam

ple of measures: The working limit switch and the safety limit switch should be separated in distance, Instructions

should be given how to use the emergency stops.

Frequent electrically uncontrolled stops will increase the wear of the crane considerably.

An uncontrolled stop is defined by loosing the crane contactors on-state annunciation signal while the brake is

lifted by the ASTAT control system. This supervision is turned on with parameter 22.03.

If the above state is declared DO no. 8 of DATX 110 will open. It cannot be closed or the ASTAT will not be ready

for new service until the 230 (115) V AC control voltage has been off and on again.

This function is not available for share motion drives.

This function is available from AST10_03A.
