Technical Specifications - hager MZ901 Manual Del Usaurio

For the front functioning modes "off & on" and
"auto", the remote controls "on", "off", "reset" and
" " are operational (input n°2 - n°8).
These control settings can be made operational by a
direct contact such as a pushbutton
or closing switch (e.g. automation, supervisor, clocks
etc.).
"on" remote control (input n°2)
It is jammed when:
• The selector or the controls activate "reset" or
" " functions,
• Safety time delay is in progress,
• Trippings = 3 (end of cycle)
• The contacts are soldered.
"off" remote control (input n°4)
Takes priority for "on" setting and automatic
reclosing.
It is jammed when:
• Selector activates the "reset" or "
• The contacts are soldered.
"reset" remote control (input n°6)
This control padlocks to the «on»position, the «off»
position and reinitialises the product.
The initialisation consists of resetting the number of
tripping and the time delay (3 mins or 30 secs).
This will remotely unjam the product.
" " remote control (input n°8)
This control locks "on" and automatic reclosing.
"off" is available.
The product does not operate if this control
is not connected (minimum).
Side selector "time set"
Time delay of 3 mins is recommended for
associated products before activating either remote
control setting "on" or automatic reclosing. Even if
it the device is reset before 3 mins the action will
be delayed.
However, for specific installations, when a continuity
of service is required, the side selector can be set at
30 secs (except for MCBs and RCBOs).
Supervision
"a" and "b" signal outputs
If "a" and "b" are closed (the position of the
associated product or remote control auxiliary
handles is down), the cause could be:
• short-circuit, an overload or an earth leakage fault
(depending on the associated device),
• tripping = 3 (end of cycle).
If "a" and "b" are open (position of the handle
down or central), the cause could be:
• padlocking " " position, or "reset" position
selected by either remote control or manually
• controlled device out of order,
• a safety time delay is in progress.
Indicator light c
The indicator light shows the state of the product
and allows a diagnosis.
We can distinguish 3 general cases:
• indicator light on, the product is operational,
• indicator light off, the product is not supplied,
• indicator light intermittent, the remote controls or
the automatic reclosing temporarily or permanently
jammed.
Caused by
- Front selector padlocking position selected
Remote control "reset" or "
- Timer delay activated
- 3 trippings end of cycle.
If a red intermittent light is present, the controlled
device is out of order.

Particular functioning modes
Power interruption
When the power is interrupted, the product
saves its state (time delays, handle position
and number of trippings) in order to reset when
the power supply returns.
During the interruption, the indicator light and
the contacts "a" and "b" are open.
If a control disappears during an interruption,
it is not executed when there is supply.
Soldered contacts on the associated product
In this case, the handle of the remote auxiliary
positions itself in the centre as the handle of
the associated device.
This state is indicated by:
• "a" and "b" contacts opening,
• the indicator light is intermittent red.
Forced remote closing
When "on" or automatic reclosing are jammed,
the controled device has tripped 3 times or a
time delay (3 mins or 30 secs) is present, it is
possible to reactivate them.
To unjam "on" remotely, we must activate
"reset".
To unjam locally, we must hold the side
selector in "reset" position (for 5 s) until a
green indicator light appears.
To reinitialise the automatic resetting remotely,
activate "reset" and then "on".
To reinitialise locally, hold the side selector in
the "reset" position (for 5 secs) until a green
indicator light appears.
Remote control impossible when tripping
(overload or short-circuit)
It is impossible to impose a manual setting
after tripping. To reset, cable the contacts "a"
and "b" in order and connect them on "reset"
control (input n°6)
Auxiliaries CZ001, MZ201 to MZ209:
These products do not operate with MZ901
and MZ911.
