Safety instructions
Bosch Rexroth AG, M-.SE 6 ...XD..., RE22047-XD-B/02.19
▶
With a 4/2 directional seat valve with Plus-1 subplate, the minimum pressure
must be 8 bar and the minimum flow must be 3 l/min.
▶
Ports P, A, and T with a 3/2 directional seat valve and/or P, A, B, and T with
a 4/2 directional seat valve are clearly assigned according to their function and
must not be arbitrarily exchanged or closed. The flow is only admissible in the
direction of arrow specified in the "Data sheet 22047-XD"
▶
Switching off the valve solenoid results in a voltage peak due to the inductive
effect. The valve solenoid already contains a interference protection circuit
dampening this voltage peak. However, additional external switching measures
have to be taken if required, in order to avoid connected electric circuits being
influenced by the residual voltage peak. The values for the residual voltage peak
depend on the valve solenoid used, see "Data sheet 22047-XD".
2.8 Personal protective equipment
The machine end-user must provide the personal protective equipment
(such as gloves, working shoes, safety goggles, working clothes, etc.).
2.9 Obligations of the machine end-user
The machine end-user is obligated to check in the order confirmation whether
the delivered valve corresponds to the required category and associated zone.
The machine end-user of the Bosch Rexroth valve is responsible that
• the valve is only being used according to the intended use as defined in these
operating instructions.
• the valve is only stored, operated and maintained according to the technical
data, operating and environmental conditions indicated in the "Data sheet 22047-
XD", in particular that the limit values indicated in the "Data sheet 22047-XD" are
not exceeded.
• the applicable provisions, rules and directives on explosion protection are being
complied with.
• the operating personnel are instructed at regular intervals.
• a danger zone is marked, if required.
• the safety measures for their specific area of application of the valve are
complied with.
