History menu
‚
The "history" menu contains all the information concerning the latest
shutdowns. The structure of those menus is identical to the structure
of the safeties menu. Whenever a failure is solved and the operator
performs a reset, the concerning data from the safeties menu is
copied into the history menu.
Additionally, the number of safeties that has already occurred, can be
consulted on the first line of the history screens.

Input/output status menu
Ÿ
The "input/output status" menu gives the status of all the digital
inputs and outputs and the changeable digital inputs of the unit.

To consult time and date information.
To consult additional information about
the unit such as the unit type, number of
circuits and evaporators and the
refrigerant used.
To consult additional information about
the unit such as the fan type, Volt
Ampere option, if there is a second
pump or heater tape present and the
quantity of digital outputs that can
possibly be used in case of non-inverter
fans (
ST
) or inverter fans (
INV
).
To consult information about the
controller's software version.
To check whether or not the emergency
stop device is active and if there is any
water flow to the evaporator.
To check the status of the heater tape
and the state of the pump interlock and
pump.
To check the status of the high pressure
switch, the reverse phase protector and
the overcurrent relay of circuit 1.
To check the fan overcurrent status of
circuit 1.
To check the status of the high pressure
switch, the reverse phase protector and
the overcurrent relay of circuit 2 (only
for EWAQ130~260).
To check the fan overcurrent status of
circuit 2 (only for EWAQ130~260).
To check the status of the compressors
11/12/21/22.
To check the status of the fanspeed
relays of circuit 1.
To check the status of the fanspeed
relays of circuit
2 (only for
EWAQ130~260).
To check the status of the changeable
digital inputs. (first screen)
Note that for a unit in a DICN system,
the inputs apply to this unit.
It will be the remote input on the master
unit however, that will be determining
for the operation of the unit.
