• Double pump:
The relationships between possible faults and the reactions of light signals and
signal contacts depend on the following factors:
• Parametrisation of signal contacts in individual operation/individual fault sig-
nal or joint operation/collective fault signal (function see Table 2)
• Allocation of “Ext. Off” control inputs to master and slave
Operating element
