Sentry Digital Panel Indicator Setup Guide Introduction This Setup Guide describes how to install and configure your instrument. This instrument is marked with the international hazard symbol. It is important to read this Setup Guide before installing or commissioning your panel meter as it contains important information relating to safety and Electromagnetic Compatibility EMC.
Sentry Digital Panel Indicator Setup Guide Installation To install your instrument, you will need to carry out the following steps: • • • Apply the engineering units label to the right-hand side of the display panel. A sheet of labels covering the most commonly used engineering units is supplied with all units. If the unit you require is not on the sheet, a blank label is provided on which you can use LETRASET™. Install the instrument into a panel. Make connections to the instrument.

Insert the instrument into the panel from the front, pushing it through as far as the front lip, to ensure correct seating of the rubber seal between the panel and the unit. 4. Working from behind the panel, take the mounting clamp, slide over the rear of the instrument and push forwards. 5.
Sentry Digital Panel Indicator Setup Guide Connections The diagram below shows the rear panel terminal connection arrangement. Rear Panel Terminal Connections Ensure the power supply is connected to Terminals 1 & 2 (marked N & L).

Sentry Digital Panel Indicator Setup Guide Powering the Instrument The instrument is designed to operate from an AC supply with voltages in the range 90 - 265V AC 50/60Hz mains supply with a maximum power consumption of 8VA when all outputs are fully loaded and the display has all segments illuminated. WARNING - The instrument is designed for installation in an enclosure which provides adequate protection against electric shock.
Sentry Digital Panel Indicator Setup Guide Operator Functions These functions are only available on units which have the front panel push buttons. Operator/Configuration Mode - Key Functions From the normal runtime display: Enter - Accesses the setup menus. Next - Scrolls forward through the setup menus. Up - Function Key 1 (see page 16). Down - Accesses the alarm setpoint(s). Use the Next viewing and the Enter Key for editing. Key for Star - Function Key 2 (see page 16).
Sentry Digital Panel Indicator Setup Guide The Setup Menus Next Enter Behind the Front Panel The instrument uses a single level menu structure. The menu system lists parameters (eg. inPt, unit, dP, etc.), each of which leads to a list of configurable instrument options (eg. the parameter inPt leads to the options mV, mA, VoLt etc.). To enter the setup menus: 1.
Sentry Digital Panel Indicator Setup Guide 2. Press and hold down the Enter Key for approximately 3 seconds until the display begins to flash. 3. Press the Next Key and the flashing display should be replaced with the message inPt (the first menu parameter). 4. To cycle through the menu parameters, press the Next Key repeatedly. 5. To view a menu parameter, press the Enter Key and the current option for that parameter will be displayed. 6.
Sentry Digital Panel Indicator Setup Guide b) Editing a Value Other parameters are changed by editing a value (eg. the parameter HdSP has a default numeric value of [100.0]). Press the Next Key to edit the flashing digit and the Enter Key to select the next digit for editing. The following example will show you how to edit a numeric value. We will change the high display value (labelled HdSP).

Sentry Digital Panel Indicator Setup Guide Menu Options Input Default: mV inPt Allows the input type and range to be defined. There are 12 ranges for temperature measurement available. When a thermosensor range is selected, ie. J, K, t, r, S, n or RTD, the instrument will automatically set the appropriate scaling in oC. Engineering Units Default: Eng unit Allows the user to define the units of measurement to be displayed o o in C, F and Eng (linear engineering units).
Sentry Digital Panel Indicator Setup Guide source by the instrument. When performing a rEAd input as part of the scaling process, the sensor must have the corresponding physical value applied. This may be pressure, weight, temperature etc. The instrument will sample the output from the sensor and save this as the L-ip and H-iP scaling parameters. A example of scaling: 0 - 100 mV = 0 -1000 (psi) LdSP = 0 L-iP = 0 (mV) HdSP = 1000 H-ip = 100.
Sentry Digital Panel Indicator Setup Guide Alarm Setpoint 1 SP-1 SP-2 Default: 100.0 Defines the alarm setpoint for Alarm 1 in display units. SP-3 As Alarm Setpoint 1 if Alarms 2 and 3 are fitted. Relay 1 Default: True rEL1 Defines the operation of Relay 1, which can be in either the energised alarm state (truE) or the de-energised alarm state (FLSE). rEL2 rEL3 As Relay 1 if Alarms 2 and 3 are fitted. A100 Default: 100.
Sentry Digital Panel Indicator Setup Guide Messages brk The input circuit, when measuring mV, thermocouple or RTD, has detected an open circuit sensor connection. When a sensor break is detected by the instrument, the measured value will be forced upscale causing any high alarms to be activated. undr oVEr Displayed when the measured value goes out of its allowed range, either outside the normal range of the connected thermosensor or the maximum/minimum display range for the decimal places set.
