E5-248-C1420
FRONT PANEL
The key below each digit sets the Set Time on the Subsidiary Display. The red reset
key resets the unit to zero when timing up or to the Set Time when timing down.
Direction of timing is programmable. There are several annunciators as follows:
• PROG appears in programming mode
• and indicate direction of
timing
• Various segments of the suite of mode
annunciators indicate the current mode
and status at a point in time
• Relay Symbol. Indicates whether relay
contacts are open or closed
• LEVEL EDGE RETRIG indicates
triggering mode.
• HRS MIN SEC together with the decimal
point position indicates which timing
range is selected.

BATTERY REPLACEMENT
Slide the cover backwards off the top of the timer to gain access to the two ½AA
lithium cells. Lift out each cell and observe the polarity sign on the PCB beneath it.
Ensure that the replacement batteries are inserted the correct way. You will need to
re-program the timer after replacing the batteries.
DO NOT THROW LITHIUM BATTERIES IN THE FIRE.

• 0.01 to 999.99 hours (D4)
These can be displayed as elapsed time
(time up) or time remaining (time down).
Elapsed time is annunciated with
and reset is to zero.
Time remaining is annunciated with
and reset is to Preset (t, t+ or t=).
TIMING RANGE AND DISPLAY
There are nine timing ranges and against each is given (in brackets) the flowchart
display which selects it.
PROGRAMMING
To enter programming mode press and hold the Digit 1 and Digit 2 keys together for
3 seconds until the word PROG is annunciated.
The PROG annunciator appears on the display all the time in programing but has been
omitted from the flowchart for the sake of clarity. On the flowchart the annunciators are
very much bigger in proportion to the numeric digits than the real display. This is to aid
legibility.
Whenever you enter programming mode the options and values displayed are the
ones in current use. Go through all the stages in the flowchart using S to step
backwards and forwards though the options at each stage and Reset (R) to move on
to the next stage.
Line 1
Select one of 8 timing modes which, on the flowchart (only) overflows on to line 2.
Line 3
Select one of 9 timing ranges, hours, minutes or seconds and resolution. The selection
you make here determines the range in which the Time is displayed. This stage
overflows (on the flowchart only) on to line 4.
4MN05405001E
Line 5
Here the programming sequence automatically takes one of three branches. The route
it takes depends on the timing mode selected above.
For modes ON DLY, OFF DLY, SS, RC= and RC= DLY, the sequence goes to column A
on the flowchart with the appropriate annunciator showing. For these modes you need
only one Set Time. The next press of Reset goes to line 7.
Modes RC DLY and RC require 2 Set Times. Enter t+ at B5, press Reset and enter t-
at B6.
For mode OS only you enter t, press Reset and then enter a Pulse Width. Pulse Width
(C6) is always in seconds to 2 places of decimals.
Line 7
Use the S key to step though LEVEL TRIGgered, EDGE TRIGgered and EDGE
RETRIGgerable and Reset to move on.
Line 8
Select increment time (up) in which reset is to zero or decrement (down) in which reset
is to Preset (Set Time).
Line 9
Select normally open (NO) or normally closed (NC) for the relay contacts.
At the end of the sequence, accept the settings by going through all the stages again
without making any changes.
NOTE:
You can also set any of the Set Times (t, t+, t- or t=) “on the fly” during normal
operation. To do this you use the digit keys and the Set Time appears on the
subsidiary display. If the timer is running in a cyclical mode, the Set Time which
changes when you press the keys is the one being annunciated at that instant.

WARNING
Installation and maintenance must be carried out by suitably qualified
personnel only. Hazardous voltages may be present on the connection
terminals.
Installation
This product is intended to be installed in accordance with the operating and
installation requirements of Overvoltage Category II and Pollution Degree 2 (as defined
by IEC 664).
It must be fitted in a suitable enclosure which is accessible to qualified personnel only.
The relay output circuits must be fitted with fuses suitable for the voltage and current
being switched.
Maximum fuse ratings:
250V AC @ 8A cosØ= 1 fuse rating 8A
250V AC @ 5A cosØ= 0.4 fuse rating 5A
30V DC @ 8A cosØ= 1 fuse rating 8A
All conductors carrying hazardous voltage should have external switching or
disconnect mechanisms fitted which provide at least 3 mm of contact separation in all
poles.
Failure to install or operate the unit in accordance with the above requirements
may result in the electrical safety of the unit being impaired.
Maintenance
Ensure that all power sources to the unit are isolated prior to maintenance,
inspection or cleaning.
There are no user serviceable parts inside this unit. Under no circumstances should
the case be opened.
All external wiring connections should be inspected at regular intervals. Any damaged
wiring should be replaced and any loose connections should be retightened.
Cleaning should be carried out using a dry cloth to wipe the casing of the unit.
WARNING
THIS UNIT CONTAINS A LITHIUM BATTERY AND MUST NOT BE DISPOSED
OF IN A FIRE OR EXPOSED TO TEMPERATURES BELOW -20 C OR
ABOVE +70 C.
