2.15.2. Sub Module Pumalan
Pumalan Module (Cat. No. 819223445) consists of two separate communication ports (clusters).
Pin 1-4 = first communication port Pin 5-8 = second communication port
The Pumalan pump protocol does not support Suspend/Resume commands, therefore, an external
relay connection is required.
In cases where the relay should be used, refer to Paragraph 2.9, to conduct the appropriate
connections.
