ENTER will open a submenu and select a menu item. In the Installation Wizard, NEXT will accept the data
entered and move to the next screen. SELECT will toggle between selected inputs (see CT Polarity screen), and
CLOSE will accept data and close the screen.
UP & DOWN F
UNCTIONS
Use F4 and F5 to activate the

(up) and

(down) functions (for

and

functions in the reading modes).
In data entry windows,

(up) will increase the value presented by a unit, while

(down) will decrease it by a
unit. Hold down either of the keys to change the values in steps of 10 units.
In all other windows,

(up) will move the selection bar one line up and

(down) will move it one line down.

UNCTIONS
(F2
KEY
)
In a measurement mode, use F2 to set for INFO (if the system is in automatic mode), IN/OUT (if the system is in
manual mode), or SETUP (if the system has not been installed yet).
The function of this key changes with system status (on Page 62) as follows:
INSTALL Use F2 to activate the SETUP function and run the Site Installation procedure (Page 26).
WARM UP During the warm up stage, use F2 to monitor system status (INFO function) or disconnect all
groups (IN/OUT function). However, group connection is not allowed at this stage.
RUNNING Use F2 to activate the INFO function and display a summary of the current System
Information (Page 67).
MANUAL Use F2 to activate the IN/OUT function for manual connection or disconnection of groups (see
next section for more details).
PAUSED Pressing F2 will open a message denoting the system is paused due to activation of the
inhibit signal (Page 51), even though the key tag shows different functionality.
ERROR# Use F2 to display a description of the existing error (see Troubleshooting for more details),
even though the key tag shows different functionality.

The relay terminals for the alarm are located on the back of the controller. There are 3 relay terminals
consisting of one N.O. Relay (
OFF/COM
terminals - Normally Open) & one N.C Relay (
ON/COM
terminals -
Normally Closed). The Alarm is triggered in the event of a critical error or when the system is not operating in
the Automatic Mode. The time delay for the Alarm Trigger is based on the following configuration:

All the alarm errors (E3, E5, E6, E7 & E10) are triggered when the system is in Manual / Self-Test Mode or as
mentioned above when the system is partially / completely inoperative;

The time delay for errors E6/E7 & E10 is calculated at 1,000 cycles (20 sec. at 50 Hz & 16.66 sec. at 60 Hz);

The time delay for errors E3 & E5 (usually occurring when the system is partially inoperative) is calculated
at 20,000 cycles (400 sec. at 50Hz & 333.33 sec. at 60Hz);

All the aforementioned time delay calculations are formulated as:
