APPLICATION CONDITIONS OF THE COILS

SPECIAL CONDITIONS

1. Short-circuit protection
Each solenoid must be connected in series with a fuse (max. 3 x I
60127-2-1) or motor contactor with rapid short-circuit and thermal triggering
corresponding to its rated current (the contactor being adjusted to this
current). With very small rated currents of the solenoids, a fuse with the lowest
current according to the stated IEC standard is adequate. This fuse may be
placed in the associated supply device or must be connected separately in
series. The rated voltage of the fuse must be equal to or greater than the
stated rated voltage of the solenoid. The cutoff capacity of the fuse cartridge
must be equal to or greater than the maximum expected short-circuit current
at the point of installation (usually 1500 A).
The nominal value of the fuse is quoted on the magnet.
Example
Sicherung/Fuse
0,08 A
2. Operation with associated valve body
The solenoids coil type AC10-..-.-PD73 through type AC10-..-.-PD86 may only
be operated with a matching valve body as a complete device, complying with
the following requirements:
• Materials with single and block assembly:
metal (brass, aluminium, stainless steel) or plastics (e,g, polyamide PA 6
GV ...)
ATTENTION!
When using the devices in petrol pumps for the control of
petrol in category 2, a valve body made of metal (brass,
aluminium or stainless steel) must be employed!
