Contents
1 EMU11 (24 hour) or EMU17 (7 day)
1 Panel mount bezel
1 Tamper proof cover
4 Surface mount stand offs (length 10mm)
2 Panel mount bolts
2 Self-tapping screws (No. 4 x 5/8 in) for panel mount bolts
2 Self-tapping screws (No.6 x 3/8 in) for attaching bezel to EMU11/17
Installation - Panel Mounting
For panel mounting (in panels up to 7.0mm thick
with the cut-out as shown in figure 2) the
EMU11/17 should be snapped into the bezel
supplied and secured in place by the use of the 2
No. 6 x 3/8in self-tapping screws provided as
shown in figure 3.
When selecting a position for the unit it should be
born in mind that a clearance behind the front
panel surface of 26.0mm is required over the full
area of the panel cut-out.
The unit is designed to be mounted from the front
of the panel by the following procedure:
a.
Insert the 2 bolts provided in the locations
shown in figure 4.
b. Then insert the 2 No. 4 x 5/8 in self-tapping
screws into the bolts and engage thread.
c. Make connections to the unit by wires
terminated in a Molex 4 way 7720 or similar
connector from behind the panel.
d. Insert the EMU11/17 complete with bezel into
the panel and tighten up the 2 No. 4 self-
tapping screws. The ears on the bolts will
rotate under the tightening action to clamp the
unit to the panel.
Surface Mounting
The EMU11/17 without bezel can be surface
mounted using the 4 securing holes as shown
in figure 5. The unit can be stood off from the
mounting surface by 10mm using the 4 spacers
if required. Screws are not provided and it
must be remembered that if used in this way
the EMU11/17 must be installed within a
housing or cubicle to prevent access to the
mains terminations.

Battery
This product has a factory fitted rechargeable battery. If the time controller is left with
its mains power switched off for more than 1 month the display may go blank. In this
case switch mains on, wait 30 minutes, and apply reset - see 1 before programming.
Programming
Only two setting buttons are required, Change and Program. In normal use the Change
button is used to switch ON or OFF, overriding the timeswitch until the next
programmed OFF or ON time. During programming the Change button is used to set
the hours and minutes. The Program button is only used when setting or adjusting the
clock time or the 4 programmed ON/OFF times, although it can also be used to review
the ON/OFF times once they have been set. Each time the Program button is pressed the
display will flash either the hours or minutes in turn, starting with the clock then the first
ON time, first OFF time, second ON time etc. Wherever the hours or minutes are
flashing they may be set using the Change button. Once set the Program button is
pressed again to proceed to the next stage.
Normal Operating Mode
In normal operation the PanelMaster will display the
correct time with the colon flashing. The output
status will be shown by either ON or OFF on the display.
1 To Reset Display
To clear programmes from memory and reset the time controller press and hold
down both buttons until the display goes blank.
Release buttons and display will fill with its complete
range of characters and then clear to show clock and
hour digit flashing.
You are now in the clock setting mode

All Types
Connections
Pin 1: Common.
Pin 2: Positive battery charge plus relay current. Min 0.50 mA (No relay).
Pin 3 : Relay connection.
Pin 4: Output & relay connection. NPN open connector. Max 10 mA, 47 V
A Molex 7720 4 way connector or similar is recommended.
MEU11 and MEU17 - Typical Usage
The examples in figs 6, 7 and 8 show the module driving a Shrack 48V
relay with power derived from the mains. Type RP330048 or RP331048
(Changeover contracts). In these configurations the relay pulls in at 47V
and is held at above 24V with mains voltages down to 200V.
EMU11 and EMU17 - Typical Usage
In this case the circuit in fig 6 can be used with a 10K, 3W resistor in place of the
15K, 2W resistor shown and a 1.3W zener must be connected between pins 1
and 2 of the module. The circuit in fig 7 can be used with two 5K1, 1.5W
resistors in place of the 7K5, 1W resistors shown and a 1.3W zener must be
connected between pins 1 and 2 of the module. The circuit in fig 8 can be used
with a 330nF, X 250V ac capacitor instead of the 220nf capacitor shown and a
1.3W zener must be connected between pins 1 and 2 of the module.
In all cases the zener is 47V and its cathode is connected to module pin 2.

2. Specifications
MEU11 & EMU11
● 4 ON/OFF programmes
● Easy 2 button programming
● Change/Override until next programme
● Rechargeable Metal Hydride battery back-up with 1000 hours reserve
● Requires only an external diode, resistor and relay to switch mains
● Temperature range 0° to 55°C
Operation
The programme button advances programme steps and the change
button the hours and minutes which flash. Time of day is set first
and is updated during the programming period. Programmes 1 to 4
follow. If, during programming, no button is pressed over a period
of one minute then the display will revert to normal operation. In
normal operation, pressing the change button changes the output
until the next programme step.
MEU17 & EMU17
● 6 ON/OFF programmes, daily, weekly, weekend or weekday options
● Easy 2 button programming
● Change/Override until next programme
● Rechargeable Metal Hydride battery back-up with 1000 hours reserve
● Requires only an external resistor, diode and relay to switch mains
● Temperature range 0° to 55°C
Operation
The programme button advances programme steps and the change
button then updates the item selected. Day/days of week is first to
be programmed followed by hours and minutes. The 6 ON/OFF
programmes then follow, each in the sequence day/days, hours
and minutes. If, during programming, no button is pressed over a
period of one minute then the display will revert to normal
operation. In normal operation, pressing the change button changes
the output until the next programme step.
It is possible to operate these modules from other voltages.
