Revision 1.9
Description
:
WHT Cassegrain Spectrograph
Location
: WHT Cassegrain Focus
Weight
: 1500 Kg
Preparation
Team required : 2 ( 1 mechanical & 1 Detector )
Approximate time : NA
This should be carried out at least the day before the change.
IMPORTANT : Make sure the detectors to be used are
pumped and cooled down ready to be fitted the next day.

1.
The handling trolley for the instrument to be removed from the telescope must
be lifted to the observing floor. |
|
2.
ISIS should be lifted up to the observing floor. The top of the handling
frame can be removed so that the instrument is ready to be mounted. |
|
3.
Any electronic equipment, cabling or cryostats not on the telescope should be
taken to the observing floor. |
|
4.
Any cryostats that are fitted to ISIS that are not in use elsewhere should be
mounted and the micrometers set-up. |
|
5.Clean ISIS slit. (Only clean it if you have been trained;
otherwise contact a specialist) |

3.
Lock off the telescope (Control Room). |
|
4.
Turn the Cassegrain rotator to correct angle and
line up the marks on ISIS and the A&G box. |
|
5.
Put telescope ties in on the GRACE side. |

9.
Check that ISIS lid is open. |
|
10.
Move ISIS into place and bolt on. ONE person only to check all bolts
are tight. |
|
11.
Lift down and store trolley. |
|
12.
Balance telescope. NB this should be done after cabling up and switching on
ISIS and the CCD controllers. Pre-testing can then be carried out during
balancing. |

Connect the ISIS Network to the Ethernet Switch called “PLC’s ONLY”
at A&G Box Rack -PLC#1 Two connections; Module 1756-ENBT
and the MVI56 Prosoft Module for ICS communication.
-PLC#2 One connection Module 1756-ENBT |

Connect and switch on the ISIS mains: -ISIS 24V PSU Motors. -ISIS PLC Connector Panel Junction Box
Rack & ISISP Power Amplifier Rack. (The same plug for both) -ISIS Temp. sensor
PSU. (White Mains Cable) -ISIS PLC#1 and PLC#2 connected to the
APC port 2 located at the A&G Box Rack. |

Ensure the correct length filler tube is fitted in each cryostat. HALF LENGTH
tubes are needed for cryostats mounted on RED and BLUE. |
|
21.
Set the capstans A, B & C and the rotation for each cryostat using the micrometers as per the 'Capstan Settings Book'. |
|
22.
Clamp the capstans in correct order i.e. 1st A
- the hole, 2nd B - the slot, 3rd C - the flat. To PREVENT FORMING AN
EARTH LOOP: |
