Others
Do not turn the operation time setting knob beyond the range of the
scale. To achieve higher accuracy in setting, measure the operation
time while turning the operation time setting knob.
The deviation and setting error for the operation time shows the
percent of FS. The absolute value of the deviation and setting error
will not change even if the set time is changed. The time
specifications should therefore be selected to use the operation time
as close to FS as possible.
At high temperatures, the operation voltage will be 90% or less if
voltage is applied continuously after timeout. Be sure to keep the
voltage within the allowable voltage fluctuation range.
Precautions for EN61812-1
The H2C (except for H2C-F@) as a built-in timer conforms to
EN61812-1, provided that the following conditions are satisfied.
Handling
Before dismounting the H2C from the Socket, make sure that no
voltage is imposed on any terminal of the H2C.
Applicable Sockets: P2CF-@@, P2CF-@@-E, PF085A, PL@@.
Wiring
Basic insulation is ensured between the motor circuit, clutch circuit,
and control output circuit. (However, the H2C-8 motor circuit and
clutch circuit use the same input.) Basic insulation is also ensured
between the output circuits of models with instantaneous output.
Basic insulation: Overvoltage category III, pollution degree 1 (See
note.)
Operating parts: Reinforced insulation (double insulation)
(with a clearance of 5.5 mm and a creepage distance of 5.5 mm at
240 VAC)
Output parts: Basic insulation
(with a clearance of 3.0 mm and a creepage distance of 3.0 mm at
240 VAC)
Note: Overvoltage category II, pollution degree 1 if the Timer is
mounted to the PL11 Socket.
