To remove a module:
1. Power down the S600+ before you attempt to extract a module.
Unscrew the retention screws before you attempt to remove a module. This avoids damage to the ejectors (refer to Figure 2-8).
Unlatch the ejectors for the appropriate module and pull the module clear of the case. You may need to rock the module slightly to release it from its connectors (refer to Figures 2-9 and 2-10).
To install a module:
Carefully align the module with the guides (located at the top and bottom of the case). Gently slide the module into the case until it seats fully with the appropriate connector on the backplane.
Press each of the two ejectors securely into place once the module is fully inserted.
Secure the module with the retention screws (two per board).
Installing EMC Protection
Your site may require you to install electromagnetic compatibility (EMC) shielding on the S600+ to minimize electromagnetic interference. The S600+ EMC protection kit (which came with your S600+) typically has the following components:
1 security backplate (place over the installed modules)
1 25-way EMISTOP Inline T Filter Adaptor (attach to the 25-pin socket A on the I/O module)
1 37-way EMISTOP Inline T Filter Adaptor (attach to the 37-pin socket B on the I/O module)
3 large (for 13mm cable) ferrite clamps
3 medium (for 10mm cables) ferrite clamps
1 small (for 6.5mm cables) ferrite clamp
2 M3 x 6mm screws (which secure the EMC backplate to the sides of the S600+ housing)
5 TY523 Ty-Rap self-locking cable fasteners (use as necessary to secure cables)
Note: These are standard components for a standard configuration. If your S600+ has a different configuration (for example, additional modules), you may have more components.
Install the EMC kit after you install the S600+ but before you wire the modules.
To install the EMC components:
Unscrew and remove the small Phillips-head screws on the I/O module (see Figure 2-11).
Place the security backplate over the modules already installed in the S600+ and secure the backplate to the I/O module using the two screws you removed in step 1 (see Figure 2-12).
Note: In actual operation, the two right-most slots on the S600+ shown in Figure 2-12 would either contain modules or would be covered by blanking plates.
Secure the backplate to the sides of the S600+ housing using the 2 M3 x 6mm screws.
Place and secure the 25-way and 37-way EMISTOP adaptors (see Figure 2-13) onto, respectively, sockets A and B on the I/O module (see Figure 2-14).
Wire the modules according to your site’s requirements.
Attach a small ferrite clamp onto the wiring to socket A on the I/O module. Attach large ferrite clamps onto the cables to sockets B and C (see Figure 2-14).
Attach a large ferrite clamp onto the wiring to the CPU’s power connections and one medium clamp to the COM3 and COM 4 connections (see Figure 2-15).
Attach a medium ferrite clamp onto the wiring for COMs 5, 6, and 7 and a small ferrite clamp onto the Ethernet cable (see Figure 2- 16).
This completes the installation process and provides the S600+ with EMC protection.
CPU Module (P152)
The CPU module contains the host processor and associated peripherals, which form the heart of the S600+ system. Various plug-in connections are provided on the rear backplate of the CPU module. Refer to Figure 3-1 for an illustration of the CPU module backplate and to Figure 3-2 for a schematic of the CPU power terminations. Figure 3-3 shows the wiring terminations. Additionally, the module uses connectors and jumpers, which are set at the factory prior to shipping. See Section 3.5, Jumpers for further information.
It is recommended that all wiring be made with stranded wire that is no larger than 1.5 mm2 (0.0023 in2 ) For the communication ports, wiring of 1.75 mm2 to 1.65 mm2 (0.0027 in2 to 0.0025 in2 ) is recommended. Power wiring is recommended to be 1.5 mm2 (0.0023 in2 ). Observe all local wiring practices and regulations.
Power Supply
The power connection is a plug-in, standard 5 mm pitch screw terminal block on the CPU module. The power supply connector is labeled TB1. Refer to Table 3-1 for the TB-1 pin connections.
Power the S600+ using a nominal 30 Volts dc power source capable of supplying 2 Amps. The S600+ operates between 20 and 32 Volt dc.
The startup in-rush current may draw 6 amps for approximately 100 milliseconds. This in-rush becomes significant when multiple flow computers are connected to the same power supply.
An on-board anti-surge fuse (2.5 Amp slow blow rating) protects the supply line should a fault occur within the unit.
Fully regulated 15 and 24 Volts dc supplies are also available for applications such as powering loops or pre-amplifiers. Resettable thermal fuses protect these outputs.
Watchdog Relay
A single pole, double-throw relay with Normally Open or Normally Closed terminals provides the watchdog status from pins 6, 7, and 8 of TB-1. Table 3-2 shows the TB-1 pin connections. Connection is through plug-in, standard 5 mm pitch screw terminals.
The relay is energized during normal operation. A CPU failure causes the relay to de-energize.
Note: Contact is rated at 1 Amp, 30 Volts dc and 30 Volts ac, and is a Form “C” contact.
On-Board Battery Backup
The backup battery (see Figure 3-2) retains the contents of the SRAM on the CPU module, the PC-compatible BIOS CMOS memory area, and the calendar clock. The battery, a Lithium 3.0 volt 1500 mAmp/hour unit, is user-replaceable. For further battery specifications, see the technical specification (S600+). To ensure that the battery is fully functional, the S600+ software routinely performs a regular load test on the unit.
