■Refrigerant gas leakage detection alarm function

An alarm signal is output when the refrigerant gas

would be leaked (as cooling circuit failure).

■Oil temperature warning function

A warning signal can be output when the oil temperature or air

temperature strays outside arbitrarily setting range.

■Auto tuning function

This function substantially cuts the time taken for

adjustment during trial operation by automatically setting

the gain when oil temperature control is not stable in the

factory setting status or when optimization is required.

■999-hour timer function (ON timer)

The operation start time can be set from 0 to 999

hours in one-hour units.

■Preventive maintenance function

●

A warning signal is output to notify that maintenance is

required when the air ﬁlter or condenser becomes clogged.

●

If the thermistor fails (out of control), emergency operation is

possible by selecting another operation mode.

This function minimizes the factors of line stoppages.

■

The control panel has been revamped. Data is now displayed

in an easier-to-understand format with more digits space.

The power consumption is also displayed (new function).

■

The newly adopted plug-in terminal block has enabled

tool-less connection of signal cables (simple connection).

■The increased pitch of the condenser’s ﬁns suppresses

clogging and makes cleaning easier.

(1.5 mm previously → 1.8 mm)

Machine tools ： Machining center, NC lathe, grinding machine,

NC specialized machine,

NC electric discharge machine, etc.

Industrial machine ： Molding machine, press, etc.

■

The ingress protection of the control box has been upgraded

(equivalent to IP54).

■

Electronic components resistant to sulfidization have been adopted.

■

The specifications for withstanding vibration during transport

have been upgraded to reflect actual transportation conditions.

■

The room temperature, inlet and outlet oil temperatures and other internal

data can be monitored at a personal computer using Hybrid-Win*.

This data can be displayed collectively, making it easy to grasp the

operating status.

*Hybrid-Win is a software tool for monitoring the internal status of the unit using a personal computer.

You can download the tool and its instruction manual free of charge from

the website (http://www.daikinpmc.com) after registering as a user.

*The communications cable and the monitor harness must be purchased separately.
