Penny + Giles EICT Installation And Setup Manual

INNOVATION IN MOTION
EICT
Installation and set-up guide
Model EICT is the Signal Conditioning Unit for Penny + Giles ICT range of in-cylinder displacement
transducers. It will only drive the transducers with an appropriate Sensor Calibration Module Card
(SCMC) fitted.
Important Note: It is essential that Steps 1 to 7 are completed before connecting a power
supply to the EICT. Incorrect connections may destroy EICT on power up.
Step 1 Remove the four retaining screws to release the cover. Note the position of the gasket
in the cover.
Identify the Sensor Calibration Module Card (SCMC) supplied with the ICT transducer.
Insert the SCMC card into position JP1. (See Fig.1)
Step 2 Unscrew cable glands C1 & C2. (See Fig.1). See note [4] regarding cable diameter.
Single Supply - Pass power
supply cable through gland C1 into
'SUPPLY' zone on EICT board.
Connect the power supply lead
carrying the most POSITIVE
potential (+10 to +60Vdc) to
Terminal 9 [V POS]. Connect the
power lead carrying 0V to Terminal
8 [GND].
Dual Supply - As Single Supply,
BUT, connect most negative power
lead (e.g. -15V) to Terminal 7
[VNEG]. See note [1] for 4-20 mA
output.
A power supply cable screen can be
connected to Terminal 6 [GND].
This is recommended but optional.
Consult your systems engineer if
other options required.
Firmly tighten cable gland lock nut
C1.
Step 3 Pass the ICT cable through gland C2 into 'SENSOR' zone on EICT board. Connect the ICT to
the terminals on the EICT board, as indicated below and shown in Fig.1 & Fig. 5.
Terminal 1 - ICT BLUE
Terminal 2 - ICT YELLOW
Terminal 3 - ICT GREEN
Terminal 4 - ICT Screen
If a connector option is required, either fitted to the ICT by a connector adapter kit or any
other connector system, refer to Notes [3], [4] & [5].
Firmly tighten cable gland lock nut C2.
Step 4 Locate 'jumper' JP3 on EICT board (see Fig.1). This determines the 'sense' of the
voltage/current output with respect to the ICT core position. Locate the 'jumper' in
the required position (See Fig. 2). The EICT is factory set with JP3 in position 'A'.
Step 5 Locate JP2 on EICT board (see Fig.1).
If required signal output is 0.5 - 4.5Vdc or 4 - 20 mA (i.e, no Voltage Module (VM) output
option card is fitted), fit 'jumper' into position JP2 (across terminals 1 & 2). The
EICT is factory set with 'jumper' fitted in this position. Proceed to Step 7.
If required VOLTAGE signal output is anything other than 0.5 - 4.5Vdc (An additional
Voltage Module (VM) output option card is required) then remove 'jumper' from JP2
and store on V(T) LINK PARK terminals. (see Fig.1)
Fig.1
Step 6 If Voltage Module (VM) output option card is selected, identify the VM card. Locate DIP
switch on VM card. (See Fig. 3) Select the required sensor output voltage, using the Switch
Position Matrix Guide (see Fig.4), and set the DIP switch positions accordingly.
Insert Voltage Module (VM) output option card into position JP2. Proceed to Step 7.
If a Current Module (CM) output option card is to be fitted, do not attempt to insert the
card now. Proceed with Steps 5, 7, 8 & 9 as for 0.5 - 4.5Vdc output requirement, as if NO
output option card is fitted. Then, proceed to Step 10.
Step 7 Connect a DMM to :-
Terminal 5 (OUTPUT) +V Output
Terminal 6 (GND) (0V) Ground
Set DMM range to measure output voltage.
Step 8 Move ICT core to the fully 'Lo' position (See Step 4 and Fig. 2) and power up the EICT.
Adjust 'ZERO' trim pot until the required output voltage is achieved on the DMM display.
(0.5Vdc if no output option cards are fitted in JP2)
